My previous patch is available here: https://595834.bugs.gentoo.org/attachment.cgi?id=450004. If you think that I've did something stupid-wrong there and there's a better way of doing this via Triple API, I'll gladly update the patch.


I think that you should update the triple class to return meaningful results and then also enhance Clang's search logic to find the GCC installation directory.
