Hi Kelly,

Sorry for the delay, I'm catching up on old email.

This is a very interesting approach, but it would have some serious  
startup-time implications :).  I think that clang really needs a  
configure script, which could sniff these values when the compiler is  
being built, instead of doing it on each run.  Alternatively, it  
could have some configuration file that specifies where to find stuff  
etc.  Are you still interested in working on this?
