Even compiler specific defines should be correctly identifying your compiler to be GCC when you specify this in the kit.

You probably need to install the dev package, too. Try libclang-3.9-dev.

Note that you can adapt the warnings options in Menu: Tools > Options >

different set of warning options for system includes/headers.

That's of course a hack :) The project manager is supposed to find out 
the version.
