Summary:                    [enhancement] Add GNU versions for CMakeLists.txt
processing, just like MSVC_VERSION
Description: 
It would be great to determine the version of the GNU compiler, so that options
can be avoided for older/newer versions of GCC and G++ (e.g. -Wextra, etc.).
A similar variable for VisualC++ already exists: MSVC_VERSION.

GCC/G++ already provide their version number via the macro definitions __GNUC__
(=major), __GNUC_MINOR__, __GNUC_PATCHLEVEL__.

Having GNU<LANG>_MAJOR, GNU<LANG>_MINOR, GNU<LANG>_PATCHLEVEL available for use
in CMakeLists.txt would be very useful.
