I would like to suggest a minor change to your 'calls' program. It does
not accept stdin unless you specify '-' as an argument. This can easily
be fixed by adding an extern variable:
    int anyproc;

then, inside of process(), do:
    anyproc++;

and in main(), after the  'while (EOF != getarg (argc, argv)) {'  loop, add:
    if (anyproc == 0)
        dostdin();
