I've tested the code with vc++, clang and gcc. Only gcc reports ambiguity.

It's remarkable that the following code is compiled successfully on all, even gcc:

void printer(int){}; void printer(float){};

int main() { printer(55); printer(55.1f); };

I don't know what standard said about this. But IMO two situations are equal!
