Confirmed that gcc rejects the former and accepts the latter, although the
former should probably still get a warning anyways even if it's not supposed to
error, just for being confusing (in my
biased-against-c++-things-like-overloading opinion)

Idiomatic C++ code should not warn.

Clang and ICC accept the former and reject the latter. VC++ rejects both, which
is odd.
