Done, done, done. What is missing a prototype? Printf? If so, that should be
already present in <stdio.h>

I am attaching 3rd updated version of the patch.

Regards,
Petar

Line break before the operator, not after; tabify indentation.

Braces on new line, line break after return type, space before paren,
missing prototype.
