POSIXLY_CORRECT not correctly unset in getopt.m4?

[Dustin J. Mitchell]

I just had a very long chase for a new build error that began after a
recent gnulib upgrade.  Briefly, the symptoms were that an invocation
of
  curl-config --libs
was returning nothing when run by configure on systems with older
curls.  curl-config is a shell script, which calls
  pkg-config libcurl --libs
and running either of those commands on the command line worked fine.
The end of the story is that gnulib's getopt.m4 now sets
POSIXLY_CORRECT in perpetuity, and as a result pkg-config interprets
"--libs" as a library to search for (and fails to find it), rather
than as a long option.

I re-updated my gnulib repository, and I don't see any changes to this
file, so I'm assuming that the bug is still present.  I will look for
a fix and send a patch, but I thought I would poll for corroboration
or any other information that I don't see in the archives.
