Yes, I was encountering some of that yesterday, but wasn't sure how much
of it was due to my (constantly-changing) setup while I was tweaking the
gnulib bootstrap side of things.  My testing passed only because I ended
up doing a fresh checkout every time.

Is there ever a chance that #include <hash.h> in libvirt sources will pick
up the wrong header?  That is, should we rename one of the two files to a
less-common name, then update all clients to specify which of the two
versions they are grabbing?  But that is independent of this patch.

ACK (assuming my ACK is good for much, given my relative newcomer status).

For that matter, maybe we should push yours first; the commit message in
3/4 can then use a bit of tweaking, if we then match bootstrap to
./.gnulib/build-aux/bootstrap.

I guess I should also do a followup patch to README-hacking to give the
hint about setting GNULIB_SRCDIR to reduce download time if you already
have a local copy of gnulib.git.
