error.

There are a lot of these "invalid lvalue" errors in the
build with gcc4, as well as a few "conflicting declaration"
ones.

This sf.net tracker is "smart" enough to not allow me to
submit a patch in this bug, so I've put a patch online
elsewhere:
http://koti.welho.com/vskytta/xine-lib-gcc4.patch

This patch allows successful compilation with gcc4, but I
have not tested the resulting xine-lib.  Caveat: I'm not a C
coder, so approach with caution!
