This issue is occuring on Snow Leopard with Apple's gcc-4.2 and possibly
llvm-gcc-4.2 compilers. The build fails with:
{{{

mm_malloc.h provides static inline functions like:
{{{
static __inline__ void
_mm_free (void * aligned_ptr)
{
if (aligned_ptr)
free (((void **) aligned_ptr) [-1]);
}
}}}
which get tripped up over free being defined to please_use_av_free.
