gnulib's git repository shows the following changes to the mktime module in
that period
(http://git.savannah.gnu.org/gitweb/?p=gnulib.git&a=search&h=HEAD&st=commit&s=mktime).

This looks like an upstream bug.  Can you make a test case in C which
reproduces the problem?  It is probably necessary to report the bug on their
mailing lint.
