Original commit message from CVS: 2008-02-23 Bastien Nocera <hadess@hadess.net> * configure.ac: Add checks for Flex/Yacc/Bison and other furry animals, for the new goom 2k4 based plugin * gst/goom/*: Update to use goom 2k4, uses liboil to detect CPU optimisations (not working yet), move the old plugin to... * gst/goom2k1/*: ... here, in case somebody is sick enough Fixes #515073
