I found the problem.  It's in tiffio.h (part of graphics/tiff).  In this
header, we find the following:

#ifndef NULL
# define NULL   (void *)0
#endif

This trips up g++ which wants NULL to be (0L).  A workaround is to
include stdio.h just before tiffio.h in
koffice-1.6.2/filters/krita/tiff/kis_tiff_reader.h.  A better solution
would be to adapt sys/_null.h in tiffio.h, but it may be easier to
convince KDE to make sure NULL is defined before including tiffio.h.
