Yes it will fail.  The above bug doesn't cause compilation problems
though and I'm not even sure that it is an issue on the x86 (hence the
XXX).

Is that the same architecture that Mercury's configuration script sees?
(In that case i686-apple-darwin* in the configure script should be
changed to i*86-apple-darwin*).
