Funny that gcc complains here and not in the di_info() and
debconf_progress_start() calls a few lines before. From a
cursory glance at the code (I'm no compiler), it looks like
we only exit the while loop when ok has been set to non-0,
which only happens at the same time link_waits is set.

So I don't think gcc has detected a real issue here.
