I seem to have almost completely successfully managed to suppress all my
knowledge I may once have had of how autoconf works, but...  Does this
look right?

$ V=1 make bootstrap

now gives me:

make[3]: Entering directory '/home/larsi/src/emacs/trunk/lisp'
EMACSLOADPATH= '../src/bootstrap-emacs' -batch --no-site-file --no-site-lisp --eval '(setq load-prefer-newer t)'  \
	-l bytecomp -f byte-compile-refresh-preloaded \
	-f batch-byte-compile ../lisp/dos-w32.el

make[3]: Leaving directory '/home/larsi/src/emacs/trunk/lisp'

which is what it's supposed to be, I think?  Just "make bootstrap" gives
me:

  ELC      ../lisp/dos-w32.elc
  ELC      ../lisp/dynamic-setting.elc

so I think it works, but whether that's idiomatic use of the autoconf
machinery, I'm not sure...
