xine-lib doesn't compile with gcc4. this patch fixes this problem.
Created attachment 56839 [details, diff] xine-lib-1.0-gcc4.patch
I'm trying it out right now, but with a stripped down patch which doesn't rename the vars as they seems not to change anything for the compilation, and less changes are better. Have you already submitted this upstream?
Thanks, applied the stripped patch in -r3 version of xine-lib.
