Comment (by nr):

 I just pulled from the darcs head a few days ago, so I presume I'm
 building 6.11.

 I don't know where {{{Makefile-stage1}}} comes from---maybe it is a stale
 version from a while back---but it is very, very useful.  Comparing
 {{{
 make -f Makefile dist/stage1/ZipGF.o
 }}}
 and
 {{{
 make -f Makefile-stage1 dist/stage1/ZipGF.o
 }}}
 the second is considerably faster.

 I basically am asking for a fast path to attempt to compile a .o file from
 possibly stale dependencies.  I am very, very eager to trade accuracy for
 speed here.  If something strange happens I can always resort to the full
 Makefile.
