gcc: recursive function quirk

Hi all you folks!! I'ld like to share with you the exotic piece of code following below, that I (accidentally) wrote and tripped uppon:

Vector_private__sizeofArrayCell (void)
Vector_private__sizeofArrayCell ();

Gcc doesn't complain. I think it poses an interesting (`academic') topic. Does anyone know whether gcc (3.2.2 here) rightfully:

1. Doesn't complain about the obvious infinite recursion??
and 2. Doesn't compain about the function not having a return statement to return something of `size_t'??

Any ideas/ thoughts??

Now I don't code C every day anymore, but what is wrong with this code?

I am sure gcc doesn't complain about infinite recursion. If that is what you want, fine. Infinite recursion is an execution time property, not a compiler problem.

A return statement is not needed because it is a void function.

To be correct it should be:
Vector_private__sizeofArrayCell (void)
    return Vector_private__sizeofArrayCell ();
Now it will return the correct value once forever elapses.
