Thanks for the tip, John.

My getopt man page states that getopts is preferred, so I have
modified the source to use getopts instead. I am re-running make but,
as you may have guessed, my sun workstation is a little s-l-o-w! ...I'll report back when its finished.


Nonono.  That is the shell utility getopts vs getopt.
Do "man 3 getopt" to get the page for the C library routines.

And there you find:

SYNOPSIS
     int getopt(argc, argv, optstring)
     int argc;
     char **argv;
     char *optstring;

     extern char *optarg;
     extern int optind, opterr;

So what you need actually is a definition for optind, that seems
to be missing:

Add somewhere in main() or outside it the defintion:

extern int optind;

What I do not know exactly is why gcc doesn't complain on other
OSes about the missing declaration.  (in amanda.h I find the
definition for getopt and optarg, but not for optind; actually
you better add the definition there.)
