I assume you mean that *MPICH's* mpicc has 7 command line options. Open MPI's mpicc only has 1: --showme (although it has multiple forms). It looks like we did make -show be a synonym for --showme, though.

The FAQ items I sent earlier (and the OMPI mpicc.1 man page) show how we chose to use environment variables instead of command line options for altering the wrapper compiler's behavior.
