The recent binNMU has "fixed" that, but we will see the same again with 
gcc 8 and the current check really doesn't make much sense:
# if __GNUC__ > 7
#  error 'Please use the same version of GCC and g++ for compiling MPICH and user MPI programs'
# endif

Attached is a patch to drop the whole check.
