Weird.  man getopt_long_only gives me:

SYNOPSIS
       #include <unistd.h>

       int getopt(int argc, char * const argv[],
                  const char *optstring);

       extern char *optarg;
       extern int optind, opterr, optopt;

       #define _GNU_SOURCE
       #include <getopt.h>

So AFAICT it comes from glibc.  I don't know if *bsd uses glibc, so this
may be an incompatibility I need to fix.

Only one reason:  consistency with most of the other software on my
system.  Actually, I do use tn5250_config_parse_argv() but not until
after I've extracted command line options that start with a dash.
getopt_long_only() removes options that start with a dash and passes the
rest of the command line unchanged.  Then I call
tn5250_config_parse_argv() to get the 5250 specific stuff.  Most X apps
expect to be able to specify things like -geometry or -name, things that
tn5250_config_parse_argv() doesn't understand.  The only dash options that
tn5250_config_parse_argv() does understand are -version, -ruler,
-underscores, and -ssl_verify_server.  -version I handle (as well as
--version for consistency).  -underscores is irrelevant to x5250.  -ruler
will be handled (as well as --ruler).

I think from glibc.  You could try replacing getopt_long_only() with
getopt_long() and see if that compiles.  If not, I'll need to investigate
further.  If getopt_long() doesn't work, then getopt() will but may need
some more changes (specifically the options[] array will not be used).

btw - there is a new and improved version available (version 0.1.0) at:

Thanks a ton for taking the time to look at this, Scott.
