Comment (by alandir2@…):

 I've been experiencing a build problem on Snow Leopard starting at about
 the same time, but my build failure seems to be a bit different as what's
 been described so far.  I'm attaching my log, but the key lines appear to
 be:
 {{{
 :info:build                  from
 /System/Library/Frameworks/CoreServices.framework/Headers/CoreServices.h:21,
 :info:build                  from ffmpeg_videotoolbox.c:19:

 error: no previous prototype for ‘_mm_empty’
 :info:build /usr/lib/gcc/i686-apple-darwin10/4.2.1/include/mmintrin.h:75:

 :info:build /usr/lib/gcc/i686-apple-darwin10/4.2.1/include/mmintrin.h:92:
 error: no previous prototype for ‘_m_from_int’

 ... and so on ...
 }}}

 I haven't had a chance to follow up on this, so I don't know if my
 environment is picking up a wrong "mmintrin.h" or what, but at least this
 should provide another data point into what might be going on ...
