Status changed to 'Confirmed' because the bug affects multiple users.

Also affects me since upgrading to ubuntu 13.10 last night.

stdarg.h also seems to be affected.

The following seems to work as a workaround for me:

cd /usr/lib/clang/3.2/
sudo ln -s /usr/lib/llvm-3.2/lib/clang/3.2/include

It looks like there's a mismatch between where the include files are installed to and where clang expects to find them

Diagnosed with the help of:

echo '#include <stdarg.h>' | clang -xc -v -

Thanks for the workaround: works for me. The problem is still there in vanilla 13.10.

This workaround also fixed it for me.

I'm marking this as duplicate of another similar bug, because it includes more information.
I will copy the workaround solution also there, thanks Kirit!
