Review comment:
> I know for sure that the opposite is true, e.g. passing `-fno-rtti` to
the GCC C frontend results in a compiler warning.
That is true for sure. I will try to find documentation to proof it, but
since C is a subset of C++ (actually C++ is forced to maintain compatibility
with C) I do not see any reason why C options should generate any warnings or
be rejected by C++ frontend
