Comment (by martinl):

 Replying to [comment:12 glynn]:

 > You should probably omit $(OBJDIR) from the prerequisites list
 altogether, and forcibly create it before making $(OBJDIR)/copying.h and
 $(OBJDIR)/confpams.h, e.g.:
 >
 {{{
 > default:
 >       $(MAKE) $(OBJDIR)
 >       $(MAKE) cmd
 }}}

 Done in r40060.

 > Anything to the right of a "|" in the prerequisites line indicates an
 order-only prerequisite. These are ignored when checking if a target is
 older than any of its prerequisites, but if make decides that the target
 does need to be re-built, these will be made before the commands are
 executed if they don't already exist.
 >
 > The 7.0 Makefiles generally use order-only prerequisites for the
 directory into which the target will be placed. They have to exist before
 the target can be made, but the target doesn't need to be re-made just
 because the directory has been updated.
 >
 > The main issue is that they only work correctly with make 3.81. Although
 that's been out since April 2006, some people are still using older
 versions, so they aren't generally used in 6.x (they are used in a few
 places, e.g. Rules.make, conditional upon $(BROKEN_MAKE) being defined,
 with the alternative being to unconditionally create the directory within
 the rule's commands).

 Thanks for the explanation.
