This should be a simple matter of obtaining libXmu, or just removing
the reference to libXmu from "defs.mak".  It's an extension library
belonging to X11, but I can't really tell you off the top of my head
what subroutines it defines.  Either you can get by without it, or
you will have to install it.

This shouldn't be a problem, although it still concerns me that the
"roundf" function is flagged as an implicit declaration, because it
means that "configure" is able to find the roundf() function in the
libm (math) library, but the "math.h" header file doesn't define it.
Probably "math.h" wants something defined like "-DC99", but I can't
tell without looking at the math.h file.  At any rate, the warning
message does not indicate a real error.
