[Bug fortran/33432] New: g77 extension: Support for the .XOR. operator

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The .XOR. operator is supported by several vendor compilers including IBM's XL
fortran, DEC fortran, SUN fortran and even GNU f77!

A patch has been proposed at:

See: "[PATCH] Support .XOR. as a -std=legacy extension"
http://gcc.gnu.org/ml/fortran/2007-09/msg00070.html

The only problem is that this patch rejects (with -std=gnu/legacy) a
user-implemented .XOR., which is valid Fortran 90/95/2003.
Other compilers such as ifort and sunf95 implemented .XOR. such that by default
both the intrinsic .XOR. as also a user-implemented .XOR. work; see also
