But equally __GNUC__ could appear elsewhere as part of a proper 
conditioning of the definitions.

#if __GNUC__ >= 4
#define __have_somthing
#endif
...

#ifdef __have_something
...
#endif

As we don't know what future headers will look like I'd rather just have 
the minimal bypass on __GNUC__ unless and until we find future headers 
which are partially but not fully GCC-prepared.
