Comment(by Rich D.):

 This appears to be a problem with the CPY3_IF_LT macro.
 The configure script is defining HAVE_CMOV when run without overriding the
 detection of the CPU.
 The C3 processor (except the C3-2) does not support the cmov instruction,
 so this assembly won't work.

 The ffmpeg mailing list discusses this and for that project they have
 proposed some solution.

 I am currently attempting to compile after running configure specifying
 --tune=c3 and --arch=586 --enable-mmx  and hope that this will work around
 the bug.
