--- Comment #2 from jh <191919 at gmail.com> ---
There is no module map in /usr/include (see below).

I can write one, but there are C and C++ linkages for different header files, I
can't assume they are all entern_c.

Xcode 6.1's clang (Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM
3.5svn)) compiles the code successfully with `-fmodules`.

$ cd /
$ find . -name \*modulemap\*

# System frameworks

./System/Library/PrivateFrameworks/ExchangeWebServices.framework/Versions/A/Modules/module.modulemap


# Below are the module maps in /Application/Xcode.app:
