I see.  One issue I see during x86_64-darwin testing (10.7 only?) is
that the forkgc2 test hangs and has to be killed manually.

I suspected that the 32-bit issue might be due to several stdint types
being wrong, which was just fixed on master.  At least the issue seemed
similar to PR d/104738.  I'm building a 64-bit trunk gdc as we speak in
order to try that as a bootstrap compiler for a 32-bit build.
