Buildbot failures

[Simon Josefsson]

Hi!  I returned from vacation today, and I had a look at the gnulib
buildbot summary available from:

http://autobuild.josefsson.org/gnulib/

Several modules -- acl, argmatch, backupfile, closeout, copy-file,
etc, essentially all failed modules except fts-lgpl -- now fail with
an error output like the one below.

Any ideas what may have caused this?  It seems absolute-header.m4
should have been included in the file list, but I'm not sure which
module is responsible.

Btw, is there interest in having automatic e-mails when, say, a module
becomes unbuildable, and have been in an unbuildable state for more
than, say, 5 days?  I don't like noisy e-mails, but it seems like it
should be possible to write a script that is conservative enough to
only send mails when there likely is a real problem.  Ideas on how the
logic to decide whether to send an e-mail or not should work would be
useful.  I don't think people will remember to look at the summary
page often enough to make it worthwhile.
