Can you investigate why __GNUC__ is 7 on your platform? As I said, I looked at 
the LLVM/clang 5.0.0 source code and it sets __GNUC__ to 4.

Are you using a version of clang that uses the GNU C preprocessor? If so, that 
would explain the problem. That combination is not supported, since preprocessor 
variables must describe the compiler accurately.

Also, please try the patch to lib/intprops.h that I suggested. You can find it 
here:
