Maybe we should define a fixed location or two to look for a clang_header.conf file that will list standard include locations?  Then distributions just need to provide this file, rather than having special cases for every single file.  Maybe also add an option for overriding this file so that we can easily remove all system includes from the search path for cross-compiling?

Heh, in T2 I dynamically patch in the path of the current gcc:


I can implement readdir and possibly a configure option tomorrow.
