Yes.  Thanks!

I'm not crazy about the name HAVE_MMAP_ZERO.  How about
HAVE_MMAP_UNFIXED, since the the thing you're testing is that you
can't use MAX_FIXED?  The `0' isn't a very important aspect of `mmap
(0, ..., ...)'; it's just a way of saying "any memory will do".

If you disagree, go ahead and put in the patch you've got; I'm just
objecting on the grounds that `HAVE_MMAP_ZERO' doesn't seem too
meaningful to me.
