Now seems as fine a time as any.  It is certainly better than a few  
days ago when it was broken ;-)  As far as I know, it is now  
completely compatible with the C runtime.

That seems fine to me.  That stuff is tricky to get right, and it's  
better to have it in one place.

One caveat, though.  Right now, I'm doing a bunch of truly ugly hacks  
(such as assuming that Char is basically a Word8) because Yhc didn't  
have support for Data.Bits, Data.Int and Data.Word when I started the  
project (self-hosting concerns).  If Yhc had those libraries, we  
could get rid of that crap and do it the right way.

Speak softly and drive a Sherman tank.
