+Subject: Re: sdl 64bit problem [PATCH]
+
+Le sam, 03/07/2004 � 18:20 +0200, Hans-Frieder Vogt a �crit :
+> Hi list,
+>
+> I found the problem that lead to the distorted sound in tuxracer on AMD64. It
+> may have also been the cause for the other reported sound problems with SDL.
+> The problem is not in SDL, but in SDL-mixer.
+> There, music files (*.it, and probably others as well) are incorrectly read on
+> all 64 bit architectures but Alpha, due to an incorrect data type definition.
+> The attached patch should solve the problem for all 64 bit architectures on
+> Linux, since at least cpp defines _LP64 and __LP64__ for them.
+> _LP64 indicates that long ints and pointers are 64 bits, but integers are 32
+> bits.
+> I am not sure whether the usage of _LP64 is also standard for the commercial
+> compilers, and for other Unixes, but at least Solaris 9 defines _LP64 in the
+> 64 bit environment as well.
+>
+> Josselin,
+> could you include this patch into your next debian packages?

+From: Guillaume Cottenceau <gc@mandrakesoft.com>
+
+Unfortunately, I should have double checked that the following
+fix (authored by Dave Goehrig <dave@cthulhu-burger.org>, not me),
+was really in the CVS... it's not, as of stable 1.2.3 at least.
+Please include it, it fixes a segfault on exiting a program which
+disabled MOD music during its execution.
