Define __LONG_LONG_SUPPORTED if the compiler claims to support C99.

Browse Source 
Don't set __LONG_LONG_SUPPORTED for gcc-1.  I didn't check exactly
when gcc started to support long long, but it was in the version
of gcc in FreeBSD-1.0 (gcc-2.4.5).

Other C99 features should be ifdefed similarly, but the ifdefs for
old versions of gcc will be more complicated since the features
weren't in all versions of gcc-2.
