Markus Armbruster 23373d01d9 configure: Test compiler flags
When AC_PROG_CC detects GCC, Make.mk adds a bunch of flags to CFLAGS.
Works only for flags that any version of gcc in use accepts.

Instead, make configure add the flags that actually work to CFLAGS.
This will let us add flags that work only for some compilers.

The new autoconf macros are from autoconf-archive v2015.02.24.

Unfortunately, AX_APPEND_COMPILE_FLAGS doesn't work reliably for
-Wno-*: gcc complains about unknown -Wno-foo only when other
diagnostics are being produced.  Test -Wfoo instead of -Wno-foo, and
rename to MY_APPEND_COMPILE_FLAGS.

Welcome to Empire 4, code-named Wolfpack.

Empire is a multi-player, client/server Internet based war game.

This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License (in file
`COPYING'), or (at your option) any later version.

See file `CREDITS' for a list of contributors.

Directory `doc' has additional information.  File `doc/README'
describes the files there and what they talk about.

To build the server and set up a game, follow the steps below.

(1) Unpacking the source tree

    If you downloaded a tarball, unpack it.

    If you cloned a git repository, run bootstrap.  This requires
    recent versions of Autoconf and Automake to be installed.  See
    also doc/contributing.

(2) Building a server

    Prerequisites: IEEE Std 1003.1-2001 (POSIX.1-2001), GNU make, a
    curses library, Perl, and either nroff or GNU troff (`groff').

    See file `INSTALL' for detailed compilation and installation
    instructions.  Quick guide for the impatient: run configure; make;
    make install.  The last step is optional; everything runs fine
    right from the build tree.

    If configure reports "terminfo: no" in its configuration summary,
    highlighting doesn't work in the client.  Commonly caused by not
    having development libraries installed.  On Linux, try installing
    ncurses-devel.

    If make fails without doing anything, you're probably not using
    GNU make.  Some systems have it installed as `gmake'.

    Solaris supports POSIX.1-2001, but you need to set up your
    environment for that.  Try passing
        SHELL=/usr/xpg4/bin/sh PATH=/usr/xpg6/bin:/usr/xpg4/bin:$PATH
    to make.  See standards(5) for details.

(3) Creating a game

    * Create a configuration for your game.  make install installs one
      in $prefix/etc/empire/econfig ($prefix is /usr/local unless you
      chose something else with configure).  You can use pconfig to
      create another one.

    * Edit your configuration file.  See doc/econfig for more
      information.

      Unless you put your configuration file in the default location
      (where make install installs it), you have to use -e with all
      programs to make them use your configuration.

    * Run files to set up your data directory.

    * Run fairland to create a world.  For a sample world, try
      `fairland 10 30'.  This creates file ./newcap_script, which will
      be used below.  You can edit it to change country names and
      passwords.

      Check out fairland's manual page for more information.

    * Start the server.  For development, you want to run it with -d
      in a debugger, see doc/debugging.  Do not use -d for a real
      game!

    * Log in as deity POGO with password peter.  This guide assumes
      you use the included client `empire', but other clients should
      work as well.

      For help, try `info'.

      To change the deity password, use `change re <password>'.

    * Create countries with `exec newcap_script'.

    Your game is now up!

Naturally, there's more to running a real game than that, but that's
beyond the scope of this file.
