The X.Org headers I'm more familiar with do something very much like
that, just with a little protection against the possibility of gcc
someday hitting double-digit releases (4.10 for instance):

#if defined(__GNUC__) && ((__GNUC__ * 100 + __GNUC_MINOR__) >= 303)

It looks like mesa already has that style used as well, in
src/gallium/include/pipe/p_config.h & include/KHR/khrplatform.h.

I'll submit a new patch to adopt this style for the mesa_bitcount
checks.
