/PROUG/LIKE

/PROG/ has decided to worktogether to make a telnet based multiplayerp

Here's a new, better start (autotools stuff left as an excercise to the reader):

/* TODO: Insert GNU GPL version 3 header. */
#include "config.h"
/* FUCK THE ESTABLISHMENT, YEAH, STICK IT TO THE MAN !! */
#define _GNU_SOURCE
#include <stdio.h>
#include <errno.h>
#include <getopt.h>

static void
print_help()
{
    printf("Usage: %s [OPTION]\n", program_invocation_short_name);
    puts("OPTION can be:");
    puts("  --help     Display help.");
    puts("  --version  Display version information.");
}

static void
print_version()
{
    puts("This is " PACKAGE_NAME " version " PACKAGE_VERSION ".");
}

int
main(int argc, char* argv[])
{
    for (;;) {
        static const struct long_options[] = {
            { "help", 0, NULL, 'h' },
            { "version", 0, NULL, 'v' },
            { 0, 0, 0, 0 }
        };
        int option_index = 0;
        int c = getopt_long(argc, argv, "hv", long_options, &option_index);
        if (c == -1)
            break;

        switch (c) {
        case 'h':
            print_help();
            return EXIT_SUCCESS;
        case 'v':
            print_version();
            return EXIT_SUCCESS;
        default:
            print_help();
            return EXIT_FAILURE;
        }
    }

    if (optind < argc) {
        print_help();
        return EXIT_FAILURE;
    }

    return EXIT_SUCCESS;
}

N.B. that I've never used getopt_long before, and that I didn't try to compile this code.
