using mpich 1.2.2.2 with ifc

Just this morning I compiled mpich 1.2.2.2 with ifc/icc. It turned out
that it was necessary to use ifc/icc in combination. ifc/gcc does not
work. I have not tracked this much further than that ./configure (in
MPICH) cannot determine fortran name mangling or size of fortran types
when ifc/gcc is used. Everything works fine with ifc/icc however. This is
on SuSE 7.2 using the ifc/icc Redhat 7.1 binaries.
