clang/trunk cannot compile Qt/head right now, at least under windows when
using the mingw standard library. The problem is caused by
http://llvm.org/bugs/show_bug.cgi?id=6295

Currently the code just randomly adds directories instead of guessing the
best one for this compilation. I will create a patch which fixes this under
mingw, by creating a list of available directories and choosing the "best"
one - the one with the higher version number. I did not analyze the exact
problem under Linux, I will do it later on when I come home, but my guess is
that this is something similar to the problem I see under windows.

Regarding Qt - this will need some work, and mostly time. I started working
on this in my branch:
http://qt.gitorious.org/~elcuco/qt/llvm-support/commits/llvm-support<http://qt.gitorious.org/%7Eelcuco/qt/llvm-support/commits/llvm-support>,
but IMHO most of the problems are right now in the clang part, not the
code in Qt.
