I will tell you now about a compiler which was ported to GNUstep, see http://code.google.com/p/libobjcgbarm, its license changed to GPLv2 from version 3. It was put on Usenet and the gnustep-dev mailing list. From there it wandered to a small wiki page on the gnustep site : http://wiki.gnustep.org/index.php/User_talk:Bubble.rogue

The page of GNUstep was cast from the news into the wiki 'xyzzy' the page chanted again and it became GNUstepified to http://wiki.gnustep.org/index.php/Ghack.app

The wizard's beans were on the move ...
