Yeah, I screwd up. I tried to duplicate my 14 failures today and I
could not (my other email hasn't made it to the list yet). Anyway, the
".level 1.1" in the ASM code gets rid of some warnings I get:
  /bin/sh ../libtool --mode=compile --tag=CC ../mpn/m4-ccas --m4="m4" cc
  -c -DHAVE_CONFIG_H -I. -I. -I.. -D__GMP_WITHIN_GMP -I..
