That's true, but then how can we explain the contradiction between
these 2 facts:

  . bootstrap runs "cd lisp; make all", which should compile
    progmodes/cc-*.el and mh-e/*.el according to the dependencies at
    the end of lisp/Makefile.in

  . in the 23.0.91 pretest tarball, the *.elc files have time stamps
    in the alphabetical order, which hints that they were built by
    batch-byte-recompile-directory; in particular, mh-e/*.elc files
    are NOT in the order dictated by their dependencies

What am I missing?
