This snapshot has a surprising number of fixes.
Thanks especially to Paul, Norihiro and Bruno for their patches.
The is one pending probable fix from Norihiro, but we still
lack a test case to demonstrate the problem.  Other than that,
I've just noticed that gnulib's regex-test is failing on that
AIX host and on OSX, so expect at least one more snapshot soon.
