Actually, it's more doable than you'd imagine. I've managed to get kencc 
to compile objects against the FreeBSD C headers (I can't run them, 
because I've no way to link them) by pushing something like this into 
the preprocessor stream:
#define __extension__(foo)
#define __attribute__(foo)
#define __inline
#define __func__ "foo"
#define __va_list=va_list
typedef char* va_list

and feeding it through this:
grep -v '^[ 	]*typedef.*va_list' | 9 sed 's/return \(\);/return;/g'

However, I think that a much better solution is to try to avoid using 
system headers in most ported code. The Plan9Port headers have no such 
gcc garbage, except inside a few ifdefs, and only, to my knowledge, for 
the AUTOLIB() hack.
