Ok, thanks, it makes sense. When we get to the point that the IS_NATIVE 
case is almost empty we can do that too, assuming nobody objects over 
the next couple of weeks...

By the way, two other stumbling block seem GCC_CHECK_UNWIND_GETIPINFO (I 
think it has to do with an ABI issue on darwin...), which also links and 
we can't easily move, and similarly AM_ICONV. Any suggestions about those?
