First, I'm not quite sure which 1/2 patch you're expecting this to be
compiled against.

This seems to be the only user of printf() in the code.  As such, I
really suspect it's not worth pulling in all of printf().  I'd be
willing to be convinced, but if so I need (a) a concrete usage case, and
(b) it should be a separate patch.
