Ideally, yes! I'd love for it to be a case of autodetecting the linux distro and then from that being able to infer without any further tests where the headers should be (relative to sysroot).

Exactly! That's the bug that bite me! ;-)
Especially after the refactoring that went in the last minute in the
llvm 3.0 branch...
that was actually a backport of several changes that are currently in tot.

To fix this we would have to completely disable the detection of native
system headers when the c-include-dirs has been specified, either at
configure time, or in a target config file.
