Add revision number to gcc version?

I think this is a good idea (and don't mind the idea of `svn status'
being run from gcc_update to do so), but I wonder if it's necessary to
continue to include the date in the version.c file?

I presume the main reason that the date was placed in version.c in the
first place was that we had no other way to place an overall
identifier on the tree revision with CVS.  However, SVN now gives us
one.  Including the date now just makes the version string unwieldly,
IMHO.
