But that's not what the manual says ('man mpicc').

--------------
COMMAND LINE ARGUMENTS
       -show - Show the commands that would be used without runnning them
       -help - Give short help
       -cc=name
              - Use compiler name instead of the default choice.
Use this only if the compiler is compatible
              with the MPICH library (see below)
