[Eric Blake]

The usual portability fixes; and this includes a fix that will
avoid a false positive in a future syntax check.

* .gnulib: Update to latest.

Hmm, I need to test with gcc 4.9 before pushing this patch; it
passed on Fedora 20 with gcc 4.8.3, but with new warnings being
added, I may need further patches to silence the new power of gcc.
