Comment (by chak):

 I agree that it would be interesting to get this to work.  But this won't
 be done with a couple of CFLAGS.  There is more involved, such as getting
 the runtime system compile for 64bit.  All the required code should
 already be in there (for 64bit support on other archs), but the Mac build
 currently assumes 32bit.  So, that should be split into two paths, one Mac
 32bit and one Mac 64bit (and then there is Mac ppc of course).
