Your code would violate the one definition rule if 'foo' is
instantiated with the same type in two different translation units, so
Clang should certainly issue a warning for it. However, we're not
issuing the correct warning -- there are circumstances where internal
linkage functions in header files make sense, although your code is
not such a case.
