I believe that using "%-p" instead of "%#p" would work.
The canonical meaning of "%-p" should be the very same as 
"%p", but gcc should not complain because it is
ready to parse a format string like "%-10p" (which is of
course different than "%10p").

A bit too tricky, perhaps?!

Tested on gcc 4.1.2.
