Yes, this is why I don't like declarations like that.

You have declared a char * [parameterfile] and a char [optarg]
which has be premoted to int when passed to strdup().

Before I shoot myself in the foot, I checked out getopt(3).

You need to declare:

    extern char *optarg;

I never commit to memory all this quirky stuff;  I always use man.
