	To get the absolute minimum set of defines try the following:

: adrian@radon; gcc -E -dM - < /dev/null
#define __FreeBSD__ 4 
#define __FreeBSD_cc_version 400001 
#define __i386__ 1 
#define __i386 1 
#define __GNUC_MINOR__ 7 
#define i386 1 
#define __unix 1 
#define __unix__ 1 
#define __GNUC__ 2 
#define __ELF__ 1 
#define unix 1 
: adrian@radon; 

cheers,

	Adrian
