Swap the usage of definition and declaration. </pedantic>

Actually, I'm somewhat surprised that compilers accept an ANSI prototype
followed by a K&R function definition; but both gcc 3.3 and SunPro C
accept:

    void x(void);
    void x() { return; }

Both also issue a diagnostic (gcc error, SunPro warning) about:

    void x(int);
    void x() { return; }

Learn something new every day.  At any rate, I stick to the ANSI style
for my new code.
