This is a preparation patch to integrate -Wmissing-prototypes to the
CI test robot. Clang++ is not happy with -Wmissing-prototypes:

    cc1plus: warning: command-line option '-Wmissing-prototypes' \
    is valid for C/ObjC but not for C++

Omit this flag when we are compiling a C++ source file.

Using -Wmissing-prototypes ensures we mark functions and variables as
static if we don't use them outside the translation unit.
