Hi,

The current check in MPICH forcing to use exactly the same GCC version
to build MPICH and the user programs is too restrictive. I got bitten
by this and seems to be a recurrent problem, for example, see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807666

The check was added many years ago by a problem with GCC3,
so I think it could be safely removed. Please see attached patch.

Cheers,
Ana
