MSVC only supports C99 when its needed for C++11 or some MS extension to C.

Is it worth supporting MSVC? If not, we have Intel C, Clang and Cygwin GCC
are the viable options we have on Windows (and perhaps Embarcadero, but I
haven't used C++ builder for a very long time). Even MinGW does not fully
support C99, because it depends on Microsoft's CRT. If we think MSVC and
MinGW are worth supporting, we cannot just use C99 indiscriminantly.
