Fixed bug #615 Scott McCreary 2008-08-21 10:48:14 PDT This patch adds support for Haiku. http://ports.haiku-files.org/browser/haikuports/trunk/media-libs/libsdl/SDL-1.2.13-haiku.diff Haiku is an open-source recreation of BeOS. It has better POSIX compliance than beOS did, and other improved features, which in some cases causes us to have to "undo" previous BeOS workarounds. Here's our port log entry for it, showing the steps to force the changes into configure and Makefile: http://ports.haiku-files.org/wiki/media-libs/libsdl/1.2.13/1 Note that this was only tried on 1.2.13 stable so far. Haiku is using a newer config.guess / config.sub that doesn't yet seem to be in the released libtool, so we are having to copy it in for now. http://haiku-files.org/files/optional-packages/
