[Bug c++/13374] New: int main without return isn't a problem, why ?

["tim dot coninx at pandora dot be" <gcc-bugzilla at gcc dot gnu dot org>]

I'm sorry if this is common knowledge, but I can't seem to find the correct
answer anywhere.

the following trivial code
---
#include <iostream>
using namespace std;

int main() {
	cout << "bla" << endl;
}
---
doesn't issue a error or even a warning, even though there is no return (save
the implicit 0 returnvalue)

Is this a bug or a feature ?
