  I looked into adding umaal, but it seems like I would have to make lots

  supported umlal, but I am not sure it can be handled identically.)

I went ahead and implemented umaal in valgrind, and now GMP runs fine.

Unfortunately, valgrind's mailer rejects my mail without explanation:

  You are not allowed to post to this mailing list, and your message has
  been automatically rejected.  If you think that your messages are
  being rejected in error, contact the mailing list owner at
  valgrind-developers-owner at lists.sourceforge.net.

I put the patch at http://gmplib.org/devel/ instead, for the benefit of
the GMP users.
