    Stefan,

You may have figured this out already but I figured I might as well follow
up anyway.  If you go into tech/tech.h and change "bool
TechOverridesDefault" to "extern bool TechOverridesDefault" then magic
compiles properly on Mac OS X 10.2.6.  I've also tested this trick on Red
Hat Linux 7.2 and it doesn't care either way.
