[MPlayer-dev-eng] [PATCH] -fno-strict-aliasing on gcc > 3

[Reimar Döffinger]

Hi,
due to problems with mp3lib and a recent IMHO ugly patch to ebml.c
lately, I came to the conclusion that the strict aliasing rules are evil
(or at least a PITA).
So I suggest the attached patch, that adds -fno-strict-aliasing to the
CFLAGS for any gcc >= 3.
Please comment, and fast, since otherwise I will apply Wednesday.

Greetings,
Reimar Döffinger
