mpicc has no way of knowing that an option is not supposed to work. It only knows about a small number of options that it can understand (e.g., --showme). Any other command line tokens are passed through to the underlying compiler.

More specifically: how is mpicc supposed to know that any given option was intended for mpicc and not the underlying compiler, particularly the ones that it doesn't support?
