[PATCH 21.5] External GIF support

PATCH 21.5 The GIF patents have expired. There's no reason to avoid using an external GIF library anymore. I would like to throw out our internal GIF support, because the source files have no license information in them. They are part of the GPLv3 blocker list. As it turns out, the source files we are using were forked from giflib, which is commonly used to supply GIF support (Emacs uses it, for example). However, we've missed out on further development of that library. The library is currently distributed with an MIT license, so our internal GIF support is probably okay, but I'd rather let someone else maintain the code. This patch removes the internal GIF support code and attempts to find and use giflib for GIF support. Lightly tested, but more feedback is welcome. -- Jerry James http://www.jamezone.org/ _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches
