Ohh, so ghc always produces one kind, and no amount of -m flags will
change that? I see, I thought it was like gcc that just took a flag.

Before ghc on OS X always produced 32bit, but gcc defaulted to 64bit.
So I set a bunch of flags so that whenever ghc invoked gcc it would
pass a -m32.

But if I'm understanding you correctly, the underlying issue is ghc
only being able to produce one "width", so even if the args are
consistent ghc will still be producing whatever width it was compiled

Ok, looking forward to it! I followed the directions on the wiki but
I'm a git newbie so I don't really understand its branching model.
After a clone of ghc.git, do I have the latest 7.2 or is this a stable
branch or something? I just want to make sure if I make changes I'm
working from the most up to date version.
