It has been there in older versions, too, though implemented
differently IMHO, there was no implied exit(), but the compiler added
up an infinite loop to the end of main(), which would be removed by
the optimizer if the code was found to be unreachable.

So, falling off the end of main() was always allowable.  One should
probably declare main()'s return value to void in that case, and use
-ffreestanding so the compiler doesn't complain.
