Of course the types did not match; that was obvious and the diagnostic
was quite appropriate.

There is no such thing as a C function returning polymorphic types.
If the return value is sometimes needed and is an int then, and is
sometimes not needed, the function should be defined as returning int.

Welcome back from Outer Mongolia!

There are now both American and International standards for C;
the two are technically identical for the moment.  ANS X3.159-1989
was approved in December 1989.
