So I'm guessing the FIXME is incorrect and should be removed.  Is the
one in the *nix Host.inc incorrect as well?

Also, for my own edification: I thought the host triple was the triple
to be used when the user doesn't specify one manually, aka the
"default build" triple.  If that's the case, why is mingw a more
reasonable triple than win32 for a Windows compile?  Or am I
misunderstanding the intention of the triple?

Thanks!
