Dear LazyGDB..

Not knowing much about C, I find myself confused by the following, extrapolated from some code I didn't write:

Code:

#include <stdlib.h>
#include <signal.h>

int main(int argc, char **argv)
{

        char    opt;
        char    *options = "a:de:f:l:p:";

        opt = getopt(argc, argv, options);
        printf ("Opt: %d\n",opt);

}

Linux on PowerPC:

suffix:~# ./test -a fish
Opt: 97
suffix:~# ./test
Opt: 255

Linux on i686:

vitalstatistix:~# ./test -a fish
Opt: 97
vitalstatistix:~# ./test 
Opt: -1

What is the deal?
