as far as I can see, mpicc invokes the normal (and only) gcc that is
installed (gcc 2.95.3):

coffee:>less mpicc

well, for some reason (that I couldn't figure out so far), the mpicc script
messes up the compiler, such that it cannot handle assembler code anymore.

I circumvented this now by applying Justin's trick (which gets rid of mpicc
alltogether and adds the mpi includes/libraries manually):

setenv MPICC gcc
setenv CPPFLAGS "-I/home/gm/include -I/home/gm/binary/include

setenv LDFLAGS "-L/home/gm/binary/lib -L/home/mpich/lib"

setenv LIBS "-lmpich -lgm"
