--host=none-apple-darwin works perfectly.

BTW it works even if I enable shared libraries.

./configure --host=none-apple-darwin --enable-cxx --enable-shared

make && make check succeeds.

However having to renounce to asm optimization is sad.

A couple of days ago I built gmp 4.2 just with ./configure, since I
wanted to try gmpbench. In fact it worked (however I did not make

May I ask you what the problem is with new mac intels? It's strange
that assembly optimization works for plain gmp but not for gmp-cxx.
gmp is stable enought to run a bench (and I suppose some standard
software), but fails badly on the tests (a linking problem, in fact --
I suppose it reguards libtests.a since as I said compiling gmpbench
against libgmp.a worked).

If you give me a couple of hints on what needs to be done, I can try
and investigate it further.
