We just use GLib's G_GNUC_NO_INSTRUMENT define, which should Just Work. If it
doesn't, it's likely a bug somewhere else IMHO.

My gmacros.h has:

#if     __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ > 4)
#define G_GNUC_NO_INSTRUMENT \
  __attribute__((__no_instrument_function__))
#else
#define G_GNUC_NO_INSTRUMENT
#endif

which looks ok to me.

http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

says "You may also specify attributes with `__' preceding and following each
keyword. This allows you to use them in header files without being concerned
about a possible macro of the same name. For example, you may use __noreturn__
instead of noreturn.", which is what's done here.

So to me it looks like either a gcc/cpp bug (it should ignore the #define
__no_instrument_function__ from that directfb header AFAICT), or a bug in the
directfb headers, or $somewhere else anyway.
