Subject: [PATCH] Add pointless initialisations to placate a gcc warning.

(I'm confident these can't happen. maxb is initialised whenever we
break from the first loop with y < h, and when we don't break from
that loop the second loop which uses maxb is run zero times. But gcc
can't work that out, sigh.)
