Thinking about it more, I'd also think that in addition to the basic
cross-compile case that i mentioned, it'd also cause problems when
GCC's types can be changed by use of target_flags...

Well, it's not clear to me that either of those are particularly
pretty.  (it seems that it's ... less than desirable to put info about
one language's library into the front-end of another, eh?)

I guess i'll give it a go, but I may get it totally wrong.  (I've
never hacked on gcc before.  8-)
