		to guile-1.8's API.
	  Supported by bunch of standard autoconf function tests, using results
		in config.h.
	  util/libguile.h, util/guile_STL.h: do all the dirty work

	* HACKT-00-01-04-main-00-80-69-chpsim-02-10:
	  Added missing reference-binder functor overloads with
		non-const reference argument types.  
	  Give me boost::bind or give me a headache!

		which was a stupid oversight, now enabled thanks to 
		using a quick-and-dirty template specialization functor.  


2007-01-28	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-44:
	  util/persistent_object_manager.cc: object padding and alignment
		is now a configure --enable option, for when object size
		is of greater importance.  
		Expects ENABLE_OBJECT_ALIGN_CHECKING in __config__.h.


2006-10-23	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-40-instance-01-09:
	  util/packed_array.tcc: fixed key translation, once again.  


2006-10-23	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-40-instance-01-08:
	  util/packed_array.tcc: packed_array_generic::index_to_key()
		tested and fixed key translation algorithm.  


2006-10-22	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-40-instance-01-06:
	  multikey_assoc.tcc: std::accumulate is in <numeric>, so include it.
	  Also implemented a lookup_index policy to 'handle' vector<bool> case.
		also added index_to_key translation member function.


2006-10-21	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-40-instance-01-05:
	  1-D specialization of multikey is-compact algorithms greatly
		simplified to O(N) as opposed to O(N lg N).
		Empty detection, no longer depends on the mapped_type, ever.
		Added iterator tests to util/test/sparse_collection_test.cc.


2006-10-20	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-40-instance-01-04:
	   multikey_assoc.{h,tcc}: factored out member functions
		is_compact and is_compact_slice to make them readily available
		for use with any multikey associative containers.  


2006-10-19	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-40-instance-01-01:
	  list_vector: now uses internal map instead of qmap, simplified. 


2006-09-16	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-20:
	  util/IO_utils.cc: instead of assert-failing long strings, 
		throw an exception to give the rest of the program a chance
		to continue.  


2006-09-12	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-14:
	  util/numeric/sign_traits.h: avoid repeated specialization
		for 64 longs.  


2006-08-29	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-06:
	  util/boolean_types.h: disabled && and || overloads
		to prevent accidental error and dependence on
		missing sequence point.  


2006-08-23	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-02:
	  Split-off packed_array into packed_offset_array, and
		packed_array_generic into packed_offset_array_generic, 
		where the non-offset variants assume an offest of 0's.  
	  This saves 8B of memory per packed array when offset is
		invariably 0.  


	* HACKT-00-01-04-main-00-80-01:
	  Added util/STL/back_inserter.h with valarray specialization.  


2006-08-09	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-54-prsim-07-06:
	  Added "util/utypes.h" for unsigned type aliases.  
	  Added long-forgotten "rebinder.h" file.  
	  Updated "numeric/sign_traits.h" definitions using "util/utypes.h".


2006-07-28	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-41:
	  Added util::getopt_mapped class for generalizable getopt parsing.


2006-07-25	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-35:
	  Pointer classes added relational operator member functions
		for actual address value comparison.  
		No clue what relational operators were doing before!


2006-07-14	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-29:
	  util/operators.h: use std::binary_function interface, 
		updated default template parameters, 
		redefined shift_operation as a typedef template, 
		added logical xnor and bitwise operations.  
	  Added util/numeric/sign_traits.h for metafunctions on signedness.  
	  Added util/numeric/zerodiv_detect.h to catch divide-by-zero, 
		used in util/operators.h.


2006-07-13	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-28:
	  New useful utility classes:
		util/member_select.h: makes functors out of member-selection, 
			for use with functional programming, 
			more general than std::_Select{1st,2nd}.
		util/tagged_subtype.h: for subtyping data types with
			an additional template parameter for type distinction, 
			useful for error-prevention and self-documentation.  


2006-07-04	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-24-merged-cow-07:
	  Branch merge.


2006-07-03	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-23:
	  CRITICAL BUG FIX in pointer class library:
		some_ptr assignment operator overloads used to depend
		on function argument sequencing, which is not defined by
		any standard -- re-wrote with explicit sequencing to correct.
	  First triggered with i686-apple-darwin8-gcc-4.0.1 (build 5341).
	  Thanks to Clint Kelly for reporting, and assisting with diagnosis.  


2006-07-02	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-20-cow-05:
	  Added operator overload to packed_array_generic for facilitating
		multi-dimensional compositions and concatenations.  
	  Removed requirement that resolve_sizes must result in non-zero
		size, to allow for "thin empty collections".  


2006-05-27	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-06-prsim-05-01:
	  iterator_more.h: implemented push_iterator and pusher helper function
		for stacks and queues, and set_insert_iterator (set_inserter)
		for set-like containers. 


2006-05-07	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-02:
	  More portability clean-ups for standard conformance.  


2006-05-07	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-01:
	  Clean-ups for portability sake.
	  Added util::addressof operator to assist in compiler workarounds.
		NOTE: not as powerful as boost::utility::addressof.
	  util/nested_iterator.h: use iterator_traits instead of
		iterator directly, in case pointer iterator is not wrapped.  


2006-05-06	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79:
	  util/STL/functional.h: forgot header inclusion protection, doh!


2006-05-05	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-24-merged-prsim-04-12:
	  Branch merge:
	  Minor fixes in util headers, and some metaprogramming additions.  


2006-05-04	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-22-prsim-04-09:
	  Bug fix in util/memory/free_list.h: acquiring from queue
		free_list should access the front(), not back().


2006-05-01	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-23:
	  Added support for old histedit-style editline interface, 
		so you can still use the same immaculate util::readline_wrapper
		class to interface to an underlying readline/editline 
		implementation -- all memory management automated.  
		On OS X, this now works with /usr/lib/histedit.h
		and /usr/lib/libedit.dylib, so installing a newer
		readline-wrapped editline is not necessary.  
	  The configuration step must (and already does) distinguish between
		histedit-style and readline-style interface.  
	  No changes in config/rl_l.m4 necessary.  
	  Tab-completion is still missing from editline... for now.


2006-04-30	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-22-prsim-04-04:
	  Ooops, relocated definitions in util/binders.h to namespace util, 
		rather than namespace std.  (For shame!)
	  Also added util/reference_wrapper.h, to try to replace 
		argval reference binders.
	  util/type_traits: Added is_pointer/remove_pointer/add_pointer, 
		volatile family, is_integral, is_floating_point, 
		is_arithmetic.  
	  Added: util/call_traits.h -- parameter traits.  
	  Removed: util/const_traits.h -- deprecated in favor of call_traits.


2006-04-26	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-21:
	  Inlined bunch of ring_node basic methods, even though we no longer
		use ring_nodes in hackt.  


2006-04-26	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-20-merged-icc-01-04:
	  Merge of portability fixes, and configurability improvements.  
	  Many template-related issues, and template library issues resolved.


2006-04-25	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-19-icc-01-03:
	  Memory pools' operator new prototypes' arguments changed from
		void*& to void*.  
		Added missing placement delete operator (no-op).  
	  chunk_map_pool.tcc: offset calculation now uses 
		RandomIterator distance to avoid using reinterpret_cast.  
	  Added util/STL/functional.h for confgure-dependent deficiencies
		with std::_Identity, _Select1st, _Select2nd.  
	  util/multikey.h: extra parens around address-of operand.  
	  util/test/Makefile.am: use configure-generated @*_WARN_FLAGS@,
		eliminated -pipe flag.  
	  util/test/test-expect.sh.in: redirection fix.  


2006-04-24	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-19-icc-01-02:
	  Significant configuration improvements regarding standard
		hash_map and friends.  


2006-04-23	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-19-icc-01-01:
	  Batch of minor header adjustments for icc's sake. 
	  util/hash_specializations.h: using reinterpret_cast for pointer.
	  util/inttypes.h: conditional definition re-written without
		assuming short-circuit conditional evaluation.  
	  util/union_find.h: typo fix.
	  general: removed redundant using declarations in same namespace.  
		Added declaration prototypes for some template functions.  
	  TODO: hash_qmap and qmap are causing some problems with
		incomplete types from const_assoc_query.h.
		Now might be a good time to migrate to the original
		STL associative containers.  Proceed with caution.  


2006-04-23	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-18-merged-prsim-03-09:
	  Branch merge.  Only minor revisions and clean ups from branch.


2006-04-22	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-16-prsim-03-09:
	  Improved macro interface for stacktrace indentation.  
		STACKTRACE_INDENT_PRINT(x << y << z)
		Wrote null_stacktrace_stream_type class that works
		like an ostream, but does nothing, and always returns
		itself.  Even handles case of ostream manipulators.  
		Unforunately compiler isn't always smart enough to
		optimize-away these no-ops, so STACKTRACE_INDENT_PRINT
		is still preferred. 


2006-04-18	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-17:
	  Checking against g++-4.2 (prerelease) which has removed the
		undocumented extension of binding template types to 
		those with greater number of template parameter, with
		trailing parameters bound to their default arguments.  
		See http://gcc.gnu.org/gcc-4.2/changes.html
	  So we've gone through the entire util library and fixed 
		the affected headers.  
	  Added a bunch of rebind helpers to the default template wrappers.  
	  Also some general cleanups of STL fwd. headers.  
	  Test case sources updated accordingly.  


2006-04-16	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-16-prsim-03-01:
	  member_saver defined as derivative of value_saver.  
	  Minor common cleanups in util/STL/*_fwd.h


2006-04-13	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-15:
	  Significant configure improvements, mostly dealing with
		defined integer types and library functions.
	  util/operator.h now checks for fmod and fmodf.  
	  chunk_map_pool's policy now checks for availability of 64b int type.  
	  util/FILE_fwd.h: now checks to see if forward declaration is
		already present from _FILEDEFED (defined for Solaris)
		before typedef-ing.  


2006-04-12	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-13-merged-spec-02-04:
	  Branch merge.  


2006-04-10	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-11-spec-02-02:
	  util/STL: added forward declaration headers:
		algorithm_fwd.h and iterator_fwd.h
	  util/persistent_functor.h: added a few basic
		container-of-container functors.  
	  util/IO_utils.{h,tcc}: implemented read_sequence_set_insert.


2006-04-07	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-08-prsim-02-05:
	  Added "util/value_saver.h" in the spirit of "util/member_saver.h".


2006-04-06	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-08-prsim-02-04:
	  util/static_assert.h: seperated into dependent and non-dependent
		macro for static_assert because of underlying typedef. 
	  util/const_traits.h: considering obsoleting, in favor of
		unified util/type_traits.h.  Emptied out for now.  
	  Added util/member_saver.h template class for temporarily
		saving away a member value and restoring upon destruction.  


2006-04-03	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-07-merged-prsim-01-15:
	  Branch merge of -prsim-01 work.  
	  This branch brings some library and configure improvements.  


	* HACKT-00-01-04-main-00-78-06:
	  Afternote: no source revisions, only additions to the lib directory. 


2006-04-02	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-05-prsim-01-15:
	  Cross-checked against g++-4.1.  
	  Private copy-ctor in named_ifstream_manager befriends
		__gnu_cxx::new_allocator, if present
		(replaces std::_Construct).  


	* HACKT-00-01-04-main-00-78-05-prsim-01-14:
	  Added configure-checks for *rand48 family of stdlib functions.
	  Implemented rand48 template wrapper in util/numeric/random.*.


2006-03-30	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-05-prsim-01-11:
	  Added util/named_ifstream_manager.{h,cc}, spawned from external 
		lexer/file_manager.{h,cc} with the following differences:
		Already seen files are also opened, AS LONG AS the are
		not currently open on the file stack, in other words, 
		cyclic file references are still caught, but once-only
		processing is not enabled for this.  
		Possible TODO: use a flag to decide opening policy.
		named_ifstream_manager also kept the include-path list
		for effective file searching.  
	  util/STL/construct_fwd.h: added some friend function macros
		for those pesky exceptional cases for std::_Construct.  


2006-03-27	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-05-prsim-01-07:
	  Fixed util/string.h: string_to_num's return value, 
		checking fail or bad-bit from istringstream.


2006-03-15	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-01:
	  list_vector_pool, chunk_map_pool: added rebind template typedef, 
		improved class member definition macros to be generalizable
		to simple templates (as long as commas don't interfere with
		the C preprocessor...) and other macro fixes.  


2006-03-14	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-19-connect-02-09:
	  There've been minor tweaks to the ring_node and union_find code.
		ring_node code is no longer used for the hackt project.  
	  Added util/test/hash_map_iterator_O2_bug.cc test to test dir
		which covers a known -O2 wrong-code bug in Apple's g++-3.3.
		We've safely worked around it in the main source.  
	  Minor g++-4.1 fixes applied.  


2006-02-25	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-18:
	  Finished writing union_find classes, including test case.
	  Updated all tests in util/test/ with #undef NDEBUG.


2006-02-24	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-17-merged-maintainence-05:
	  Maintainence branch merge.  


	* HACKT-00-01-04-main-00-77-16-maintainence-05:
	  Added configure-wrapped "util/xdr.h"
	  Suppressing LIBS in the util/test directory.  


2006-02-23	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-16-maintainence-04:
	  Applied __ATTRIBUTE_MALLOC__ to memory pool allocators.  
	  Properly detect and use __builtin_expect "in util/likely.h".


2006-02-20	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-11:
	  Checked against g++-4.1 (RC1) [prerelease 20060219].  
		configure now checks for presence of reverse_iterator
		comparisons for conditional use in 
		"util/STL/reverse_iterator.h".
	  const_assoc_query.tcc: qualified call to parent method find().


2006-02-14	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-10+:
	  Disabled integer_traits_test #13 because 13! overflows 32b, DUH!


2006-02-12	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-10:
	  Made libraries usable with -DNDEBUG with appropriate use
		of __ATTRIBUTE_UNUSED__ around unused assertion variables.  
	  util/attributes.h: now uses config.h to conditionally define
		some attribute macros.  
	  Test cases in util/test, however, force-undefine NDEBUG.


2006-02-06	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-4-preal-01-03:
	  util/operators.h: added functor specializations for 
		the modulus<float> and modulus<double>.  
	  parser::arith_expr::check_meta_expr(), added check for
		operating on pair of real-valued operands.  


2006-02-04	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-76-8-merged-spec-01-04:
	  Branch merge, contains a few critical fixes, and minor improvements.  


2006-02-03	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-76-7-spec-01-04:
	  Critical fix in util/IO_utils.tcc:
		implementations of sequence readers and writers uses
		value_writer and value_reader template functors.  
		This way, it can pick up specializations.  
	  Minor improvement: persistent_functors were changed to
		non-template classes with template forwarding () operator.  


2006-02-03	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-76-7-spec-01-03:
	  Added "util/visitor_functor.h" to provide convenient bound
		functors for easy visiting over iterated structures.  


2006-01-31	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-76-6:
	  Fixed critical bug in multikey_assoc::is_compact_slice, 
		and simplified it to be less recursive.
	  Also updated util test suite with smaller example.  


2006-01-26	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-76.2:
	  Temporary char buffer array now uses excl_array_ptr, 
		in persistent_object_manager.cc.
	  Improved interface to util::wtf.


2006-01-22	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-74:
	  Minor prototype fix for setvbuf in util/libc.h.


	* HACKT-00-01-04-main-00-73-merged-prsim-00-34:
	  Branch merge.  Includes revisions from -prsim-00 and 
		-PRS-03 branches.
	  Includes the fixes and clean-ups listed below.
	  Much improved configurability.  


2006-01-20	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-PRS-03-02:
	  Added some handy persistent template functions in
		"util/persistent_functor.{h,tcc}", some in the style
		of util/IO_utils {read,write}_sequence_* functions.  
		These versions also propagate a persistent_object_manager
		reference (bound to functor), and cell the canonical 
		persistence member functions: collect_transient_info, 
		write_object, load_object.  
	  Minor enhancement to persistent_object_manager::read_pointer_list<>
		by using smart call to util::reserve().  
	  In util/IO_utils: read_sequence_realloc, for safety, inserted
		a call to the dtor of the argument valarray prior to 
		placement construction.  


2005-01-18	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-25:
	  Configuration and portability update only.  


2005-01-17	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-24:
	  MAJOR round of clean-up.
	  pointer_classes: owning, sharing and deleting pointer classes
		now use a deallocation_policy template argument, 
		that defaults to delete_tag (single-alloc deletion).
		Variants are defined in terms of the other 
		deallocation_policy tags.
		This results in FAR cleaner code in "excl_*_ptr.h"
		eliminating the old preprocessor name hacks. 
		The non-default variants however are defined as 
		nested typedefs, such as excl_malloc_ptr<T>::type.  
		These may be less convenient, however, the non-default
		uses are discouraged in-place of more conventional methods, 
		such as using a vector instead of managing new [].  
		Essentially the non-default uses should be infrequent.  
	  util/STL/{list,map}.{h,tcc} are now obsolete, just use <list>
		and <map>.  For now they remain in the repository but
		are not distributed.  Attempts to include them will #error.  
	  util/STL/*_fwd.h: all define a default_* struct with a
		::type member typedefed to the default arguments.
		e.g. template <class T> std::default_vector {
			typedef	vector<T, allocator<T> >	type;
		};
		Now you can use non-macro'd forward declarations when 
		the definition for a type is not required.  
	  util/stacktrace.h: deleted USING_STACKTRACE macro.


	* HACKT-00-01-04-main-00-72-prsim-00-23:
	  Added (not used yet) deallocation policy classes to util/memory.
	  It's about time we do this because of the need to handle 
		other types of deallocation-like activity using 
		pointer-classes.  
	  Forthcoming in next revision.  


2005-01-16	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-19:
	  Fixed stupid typo in util/readline_wrap.h" in conditionally
		defining USE_READLINE... arg!
	  Added small readline_toy program in util/progs for 
		interpreter debugging, no need to compile rest of project.  
	  Added more stdio function checks in "util/libc.h"


2005-01-15	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-18:
	  Re-instated some name substitutions in the lexyacc-prefix-generator.
		Needed to disambiguate some flex symbols.  


2005-01-15	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-17-merged-temp-04:

	* HACKT-00-01-04-main-00-72-prsim-00-16-temp-04:
	  util/readline_wrap.cc: added gets() method with custom prompt arg.


2005-01-14	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-16-temp-03:
	  Moved <ctype> -related configure stuff to "util/ctype.h"
		and added a handful of conditional library checks.  
	  util/readline_wrap.cc: corrected EOF behavior for
		the case of the BSD editline library.  
	  Added util/template.h (empty) for compiler characteristic
		checks related to templates in C++.  


2005-01-13	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-16:
	  Added util/Makefile.inc: this is where this subdirectory's
		makefile management should go, it is included by
		the parent Makefile.am.  
	  Added util/lang subdirectory for language-specific
		general tools.  


2005-01-12	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-15:
	  Added "util/NULL.h" finally.
		No longer need "util/macros.h" for just the NULL definition.  
	  Added "util/FILE_fwd.h" for configuration-dependent
		forward declaration of FILE, so you won't have to include
		<stdio.h> for name-uses of FILE* anymore.  Hallelujah!
		(Falls back to including stdio if all else fails)
	  Updated many util library header files to reflect these
		updates in headers.  


2005-01-11	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-14:
	  util/memory/excl_malloc_ptr.h: const_cast away pointer type
		as it is passed to free(void*).
	  util/libc.h: configure-checked some more (unimplemented)
		standard functions.
	  util/readline_wrap.{h,cc}: folded whitespace-eating into gets(),
		factored history-adding into seperate member function.
	  Added util/tokenize.{h,cc}: default method of tokenizing
		whitespace-delimiter std::string into list<string>.  
		TODO (much later): more sophisticated command-line parsing.  


2005-01-03	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-09:
	  Untested draft of unique_ptr in "util/memory/unique_ptr.h".
	  Added another class to util/static_trace.{h,cc} for debugging
		in the middle of a module's static initialization/destruction.  


2005-12-22	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-05:
	  Added visitee class template.  
	  Added offset_array array wrapper template. 


2005-12-15	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-04:
	  Added "using clear" to util::memory::index_pool for 
		en masse deallocation.  


2005-12-14	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-03:
	  Created util/memory/index_pool.h which is an adapter to turn
		any vector-like container into an index-based allocator.  
	  Wrote util/memory/free_list adapter helper function to
		use any of several standard containers as free-list, 
		primarily use for memory-management.  


2005-12-13	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-prsim-00-02:
	  Added "util/string.h" to configure-wrap around string.h, strings.h
		and cstring, and provide some handy inline functions
		in the util::string namespace.  
	  util/readline_wrap.cc: configure dependencies on some readline
		prototypes' (const-incorrect) argument types.  
	  util/readline.h: configure-wrapped inclusion of the proper
		readline header.  


2005-12-12	David Fang		<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-72-merged-rename-00-06:
	  Merge from rename-00 branch.  
	  Some comments updated.  


2005-12-09	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-71:
	  Library additions:
		enhanced excl_ptr and count_ptr families of pointer classes
		to be able to define new classes with different delete
		policies (e.g. array [], malloc).
		This is accomplished by making the original header file
		template-able, via preprocessing magic.  
		Added a few basic tests for these new pointer classes.  
	  Added util/readline_wrap.{h,cc}, configured readline header
		providing a consistent (limited) common interface.  
		Since read line are malloc-allocated, we use an
		excl_malloc_ptr to manage the memory for it.  HUGE!
	  Added libc.h and libc.c as configurable workarounds for systems
		lacking the essential library functions (in C).  
	  Corrected configurability of util/STL/hash_map.h.


2005-12-07	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-70:
	  Configure-checked for [u]int64_t in "inttypes.h", "bitset.h",
		"numeric/inttype_traits.h", "numeric/bigger_ints.h".


2005-11-09	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-66-merged-parser-03-10:
	  Merged branch revisions to trunk.  


	* ARTXX-00-01-04-main-00-65-parser-03-10:
	  Added util/file_status.h for consistent use of file return
		statuses, includes a meaningful enumeration.  


2005-11-07	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-65-parser-03-07:
	  Gave unique_list::push* return value, indictaing whether or
		not the value pushed already existed in set.  


2005-11-07	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-65-parser-03-05:
	  Added configured util/dirent.h, and wrapper functions direct.cc.
	  Typo fix in unique_list::push() parameter.


2005-11-06	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-65-parser-03-03:
	  Added util/unique_stack.{h,tcc}.
	  Completed more list interface to unique_list.


2005-10-25	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-61-merged-PRS-02-11:
	  Merged revisions to trunk.  


2005-10-16	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-60-PRS-02-09:
	  Determining containership in util::unique_list fixed. 
		It was just plain wrong before.  (Fortunately, never used.)


2005-10-13	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-60-PRS-02-08:
	  Added associativity (is_associative) virtual function to
		binary arithmetic operators in "util/operators.h".


2005-10-07	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-60-merged-cflat-01-11:
	  Merged branch revisions to trunk.  


2005-10-06	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-59-cflat-01-09:
	  Fixed false positive warning condition at the end of
		persistent_object_manager loading.  
		Allow shared visit to classify as owning an entry.  


	* ARTXX-00-01-04-main-00-59-cflat-01-08:
	  util/ptrs_functional.h: changed inline mem_fun (const versions)
		to take argument of type const P<const T> instead of
		just const P<T>.  (Likewise in the functor classes.)
		g++-3.3 through 4.0.1 accepted this, but 4.0.2 rejected 
		(no match found).  This revision make the code more correct, 
		and is accepted by all versions to date.  
		(FYI: case was submitted as PR 24243 to gcc-bugzilla)


2005-10-05	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-59-cflat-01-06:
	  Added BOUNDS_CHECK() assertion to "util/macros.h".


2005-10-03	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-59-cflat-01-05:
	  Fixed typo in list_vector::swap().  
	  IO_utils.{h,tcc}: added util::read_sequence_prealloc
		specially for valarray reconstruction (uses placement ctor).  


2005-09-05	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-58:
	  Fixed some \file doxygen commands in comments in a few headers.  


2005-09-04	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-56-merged-footprint-01-26:
	  Merged fixes and enhancements from -footprint branch.  


2005-08-28	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-55-footprint-01-27:
	  Added explicit instantiation macro to mutikey_generic
		constructor (from non-generic multikey).  


2005-08-21	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-55-footprint-01-19:
	  list_vector: (bug fix) wrote custom copy-constructor because
		structure contains raw pointers, which must be relinked
		upon copy.  


2005-08-19	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-55-footprint-01-16:
	  Added STACKTRACE_INDENT macro to stacktrace.h to allow users
		to print stacktrace prefix before diagnostic messages.  
	  auto_indenter manipulators in indent and stacktrace declared const.


2005-08-15	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-55-footprint-01-08:
	  util/static_assert.h: uses typedef rather than static const value.  


2005-08-15	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-55-footprint-01-07:
	  Using enhanced header configuration, we've "config-ed" many 
		util headers with the results from "config.h"
		header existence and usability tests.  
	  Also now enforcing -Wunnused except for -Wno-unused-parameter.


2005-08-08	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-54-macros-02:
	  Standardized some stacktrace macros for _PERSISTENT and _DTOR
		and _CTOR, because they were blatantly copied everywhere
		before.  Now they are available for each module
		to enable or disable.  
	  Added pointer-class-specific assertion macros, versions
		of NEVER_NULL and INVARIANT to control debug level
		of the most commonly used templates.  
		Each module may alter the debug mode or use the default.  


2005-08-06	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-53-unique-01-07:
	  Fixed bug in ring_node:
		iterator copy-constructor wrongly asserted condition, 
		now we allow copy-constructor to call an unchecked constructor
		because the source is already a valid iterator.  


2005-08-05	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-53-unique-01-03:
	  Cleaned up list_vector.{h,tcc} some.  


	* ARTXX-00-01-04-main-00-53-unique-01-02:
	  Added bitset placeholder class, intending to extend
		std::bitset with arithmetic functionality later.
	  util/inttypes.h: configure-dependent wrapper to standard headers.
	  util/numeric/bigger_ints.h: definitions of larger synthesized
		integer types.
	  util/numeric/inttype_traits.h: relationships between
		next larger/smaller integer types.  
	  util/numeric/nibble_tables.h: generalized MSB_position.  
	  util/static_assert.h: like compile-time constraint/concept check.
	  Working towards more extendable chunk_map_pool, 
		allowing for bigger chunks (64 now enabled by uin64).
	  util/test/chunk_map_pool_test.cc:
		added (disabled) checks for huge chunked-pools.  
		Need to turn them on by hand and hand-check.  


2005-07-15	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-30:
	  Added front() and back() interface to packed_array[_generic].
	  Added "util/wtf.h" as developer tool for figuring out
		the canonical type of a typename/typedef and 
		the type of an object, e.g. return type.  


2005-07-14	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-28-subinstance-07:
	  Critical bug fix in multikey_generic<>::operator =:
		detected self-assignment (alias) condition
		and avoid self-destruction.  Hello?  C++ 101.  
		Strangely, this problem only exhibited on a linux build...


2005-07-12	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-28-subinstance-04:
	  util/ring_node.h:
		Added default iterator structs for convenience.
		Sometimes necessary when wanting to refer to 
		ring_node_derived<incomplete type>.


2005-07-06	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-06-actuals-16:
	  Cleaned up "util/multidimensional_sparse_set.tcc"
		iterator construction over assignment, 
		new flexible template methods for key method functions:
		add_ranges() and query_compact_dimensions().
	  Fixed (and used, and tested) "util/reserve.h".


2005-07-05	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-06-actuals-14:
	  Added "util/reserve.h" policy for vector-like memory reserve
		when possible -- for other non-vectors, it no-ops.


2005-07-03	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-06-actuals-10:
	  Fixed scalar initialization bug in util::multikey_generic, 
		where passing in 0 dimension would result in
		allocating size_t(-1) size array in constructor. 
		Moral of lesson: look before you subtract one.  
		(Updated bunch of multikey_generic's constructors)
	  Fixed multikey_generic assignment (=) bug:
		default assignment semantics for valarray (implementation type)
		are insufficient: defaults to truncated copy.
		We replaced with proper reallocation (vector-style)
		assignment, with explicit destruction and placement
		copy-construction.  
	  Eliminated copy-modified specialization of packed_array<bool>
		and replaced it with a packed_array_implementation
		policy class, with specialized types for bool case.  
		Result: much code reduction for equivalent functionality.
	  Updated pretty-print dump for all packed_array*.
		Includes a nice multidimensional array dump.  
	  Also added a test to packed_array_test to check for this.  
	  While I was at it, replaced iterator initialization
		with construction where possible in util::multikey*
		and util::packed_array*.


2005-06-30	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-06-actuals-07:
	  Added explicit instantiation macros to "util/multikey.tcc".


2005-06-21	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-48-connect-01-06-actuals-02:
	  Figured out how to automatically generate unique identifiers
		using cpp, after discovering macro tricks on the web.  
	  "util/indent.h" and "util/stacktrace.h" now use these macros.
	  No more shadowing identifier conflicts!  Hallelujah!


2005-06-21	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-45-merged-anal-04:
	  Merge to trunk.  


	* ARTXX-00-01-04-main-00-44-anal-04:
	  Tiny patches after cross-checking against different gcc versions
		on different platforms.  

	* ARTXX-00-01-04-main-00-44-anal-03:
	  Updated a bunch of files to conform to new warning strictness, 
		describe in src/ChangeLog (same entry).
	  persistent_object_manager's indices have been updated to
		size_t (unsigned int) type.  


2005-06-20	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-44-anal-02:
	  Every util/.tcc file has been updated with the following
		macros for controlling template instantiation:
		EXTERN_TEMPLATE_<file-name>
			predefine to suppress template method definitions
			and only include the .h header of the same class(es).
		EXCLUDE_DEPENDENT_TEMPLATES_<file-name>
			predefine to exclude the template definitions
			that this file/class depends on.  
	  By default, when the user does nothing different, all dependent
		definitions are included recursively in .tcc files.  
		So If you don't even think about it, it just works.  
	  We now explicitly suppress template instantiation by *hiding*
		the complete template definition when the above macros
		are used.  Since -pendantic was added to the compiler 
		dialiect flags, replace "extern template" with these
		macros.  
	  Caveat: There can be cross-interactive effects between 
		multiple .tcc files that share the same dependencies, 
		so be warned.  You can always diagnose a problem
		by using -save-temps and examining the .ii files.  


2005-06-14	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-42-CHP-01-19:
	  Provided INDENT_SOURCE() macro in "util/indent.h".


2005-06-08	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-42-CHP-01-09-dataexpr-10:
	  Adding -Wundef to CFLAGS caught an unremoved obsolete conditional
		in "util/packed_array_fwd.h", harmless, but fixed.  


2005-06-06	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-42-CHP-01-09-dataexpr-06:
	  util/memory/ref_count_pool.h:
		removed cyclic header dependence on count_ptr.h, 
		replacing with forward declarations.  


2005-05-23	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-42:
	  ptrs_functional.h: relocated to util namespace, not std anymore.  


2005-05-22	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-39:
	  Modified and verified that all headers properly standalone.
		(except using{i,o}stream.h, which aren't supposed to be.)
	  Anything that directly depends on the definition of size_t
		now includes configure-dependent "util/sizet.h".
	  Split out forward declarations of persistent.h into separate file.  


2005-05-20	David Fang		<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-38:
	  Started this ChangeLog.
	  From now on, util-library related changes should be noted here.  
	  getopt_portable.h:
		now uses conditional results of configure script in config.h.  
	  static_trace.h:
		added DEFAULT macros for convenience, now don't have to
		pass in string argument for BEGIN and END, 
		defaults to using built-in __FILE__.
