Yes you're right. But also GCC reports a warning, saying that the function is
only declared, but not defined.

This might be exactly what we want, if the function is only used at compile
time, as a kind of type mapping.

So I'm not sure, but in my opinion, if a function is declared, but not defined,
and it is used in a decltype - that is totally ok and no warning should be
omitted at all.

-Wunneeded-internal-declaration is a clang flag, not a gcc one
