No, ANSI C has always said the return type must be int, 5.1.2.2.1(1).
And you asked for pedantic mode.

IPF has a whole new C compiler.

Because void is illegal, so aC++ has always given a future error.
For PA, currently with aCC -Ae only.

More accurately, on IPF the C compiler is based on aC++.

in C++ either, 3.6.1(2).
