From: Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>
It may be useful to known the base standard and if we're using
the gnu extensions but as these are defined it can only be done
on a case-by-case basis.
Change these defines so that:
* the GNU extensions is the least significant bit
* the versions can be easily compared with <, >, <= and >=
