Clearly, we need to change the prototype for MPI_Init and MPI_Init_thread. The best choice is probably back to the original:

char ***argv_p

Agreed.

since that's what it is (complete with a rationale for why it isn't what we're currently using). I prefer this to the char (*(*(argv_p[]))), since the usual inside-out reading of that is "argv_p is an array of pointers to pointers", which isn't the intent, though it might make the compiler happy.

Agreed. 'char (*(*(argv_p[])))' is quite simply perverse and, while equivalent, will merely confuse people :-) Regards, Nick Maclaren.
