FWII: it is not valid C. Specificaly, ISO/IEC 9899:1999 (E) states the following
contraint on the return statement (6.8.4.6): A return statement with an
expression shall not appear in a function whose return type is void.

You are absolutely correct, except that it is 6.8.6.4.  So, while this
is valid C++, it is not valid C.  So it goes.
