Is mex another wrapper compiler, similar to mpicc?
If so, what you might want to do is set mpicc's underlying compiler to
be mex, and then link your application with mpicc (i.e., layer the
wrapper compilers).
You can do this by setting the environment variable LAMCC to "mex" (or
whatever the executable name is that you use to compile/link Mex
applications).
