We'll be fine :-), we're using GCC 4.8.3 on our modern builds.

We are using GCC 2.9x for the "BeOS ABI compatible" builds, but we 
forked
Mesa 7.9.2 which seems to be the absolute last version of Mesa that will
compile under GCC 2.9x :-)

Also, I sent an email about removing the SUNPRO C version checks, but it 
seems
like it was never delivered:

"
Why not also drop the SUNPRO_C version check?

#  if defined(__GNUC__) || defined(__SUNPRO_C)

I downloaded SunStudio 12 (circa 2007) and __SUNPRO_C is set to 0x590.
If we drop support for GCC 4.1 (2007), might as well drop older sun 
compilers.

#include <stdio.h>

int
main()
{
     printf("0x%X\n", __SUNPRO_C);
     return 0;
}
