Compiling with GCC 14 is known to fail for MPlayer.

I have posted a patch[1] on mplayer development mailing list, but
it will not be applied. Just highlights the places where changes
are needed.

Problem with fixing warnings is: Usually the simplest most straight
forward thing to fix the warning, makes the warning permanently
disappear and the code even more wrong than before.

I hope I can resume working on it, but currently I seriously
lack time to push it forward.
