The answer was in the manual after all, under the section "Variable
Attributes" rather than "Function Attributes" (where I had already
looked).  This could be construed as a bug in the documentation!

Something like 
	extern int
	my_printf (void *my_object, const char *my_format, ...)
                  __attribute__ ((format (printf, 2, 3)));

will do the trick.  Thanks to Timothy J. Lee  <timlee@btr.com> for
pointing this out.

Greg.
