Cast to smaller integer types explicitly.
Generally avoid platform-dependent types (size_t) in simulation code.
Use float versions of math.h functions, not double.
This was SVN commit r10017.
added player_id_t typedef and INVALID_PLAYER, use that instead of -1.
also added sanity checks to cpu.cpp to ensure ARCH_* is correct (see
http://www.wildfiregames.com/forum/index.php?showtopic=13327&hl=)
and further predefined macros to arch.h just to be sure.
This was SVN commit r8079.
