Yes.
BTW, if I were to update to the latest from gnulib,
it would break "syntax-check", due to a weakness in
maint.mk's new hash.h check.

It gets a false-positive on any inclusion of libvirt's own "hash.h":

    $ git ls-files|grep hash.h
    src/util/hash.h

I haven't yet decided what to do about that.
