May I suggest that stdarg.h/varargs.h be modified to #define
_BSD_VA_LIST_ to __gnuc_va_list, possibly with appropriate ifdefs to
limit it to FreeBSD? (Is this needed by Net/OpenBSD too?) This is
simpler and less fragile than adding stuff to fixinc.
For complicated reasons related to similar interactions with glibc's
headers, I'd personally like to see the typedef name be __va_list, and
__gnuc_va_list a #define as well.
