Actually since the extension is .cc it uses g++ by default.

I understand that it is legal C++ code; I'd just like for g++ to warn about it
just like gcc does IFF I set a compiler switch warning to catch it (ie. it seems
like -Wmain-return-type).

Of course for this simple example I gave it is obvious that the compiler adding
a return of is is correct; this might not always be the case and without an
explicit statement in the code the compiler can't be sure that is what I intended.

I'm not looking to change the semantics of inserting the default; I'm just looking
for a way for me to be reminded that it is missing in case I don't want the default.

Thanks for the response,

Bill
