Hmm at least WITH_DEBUG still seems broken:

  CC     xine_real_video_decoder.lo
In file included from xine_real_video_decoder.c:49:
real_common.h:49: error: '__environ' defined both normally and as an alias
real_common.h:59: error: 'stderr' defined both normally and as an alias
gmake[2]: *** [xine_real_video_decoder.lo] Error 1

 Thanx, :)
