MacOS X Compile error with swscale

I'm using the latest svn as of this writing.

I configure ffmpeg as follows:

./configure --enable-shared --enable-gpl --disable-mmx
--enable- 
libmp3lame --disable-vhook --enable-libfaad --enable-libfaac
--enable- 
swscale

And I get the following error:

yuv2rgb.c: In function ‘yuv2rgb_get_func_ptr’:
yuv2rgb.c:609: error: ‘yuv420_rgb32_MMX2’ undeclared (first
use in

yuv2rgb.c:609: error: (Each undeclared identifier is

Looks like it's still trying to use some MMX code, even
though I  
disabled it, perhaps?  (I'm open to being completely wrong
about this.)

Hmm... ifdef, undef, define... seems a little redundant.

And again.

Am I the only one thinking this file is a bit of a mess?

MMX2 implicates MMX.
Having the defines for MMX2 set but not the ones for MMX is
a bug in 
configure IMO.

Now I get the following error, I think somewhat later on:

gcc -dynamiclib -Wl,-single_module

It is trying to use MMX2 code, not MMX code.  You could add
--disable-mmx2 to the command line to make compilation go
through
or try the patch I created to fix the situation.

That one is fixed easily.
