The 68k Freeciv (except ancient versions) doesn't work so well with OS4;
especially Roadshow causes problems. That's why I chose to put together an
English-only server (ie. no gettext) that seems to work.

Installing Freeciv: Simply copy civserver to your Freeciv directory, rename the
old first if you want. If you do not have the game yet, you can get it from
http://www.sebastianbauer.info/index.php?page=amiga/freeciv

Compiling Freeciv: The included config.h and Makefile were used to build the
server, but they may not be good for the client. vbcc and newlib is used, which
is why amigaserver.c is not. The source code is on ftp.freeciv.org
