Define __LONG_LONG_SUPPORTED if the compiler claims to support C99.
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.
