The previous Emacs trunk commit (i.e., the commit before the one that
caused you a problem) was based on gnulib 2011-05-06. I
also updated Emacs trunk from gnulib on 2011-04-26, 2011-04-17,
2011-04-10, 2011-04-06, and 2011-04-05. So if
you've been keeping up to date regularly with Emacs, your
old Makefile was based on a suitably-recent gnulib.

Perhaps you could try checking out the old version, building it, and
then doing a "bzr up", and see whether the problem recurs?
The top-level Emacs directory does have a dependency of config.status
on configure, for what that's worth, so a top-level "make" should
rebuild config.status.

His problem occurred in emacs/lib, and emacs/lib/Makefile is
generated by Automake, so I expect this is not the problem.
