I think another fix is just putting it into some other directory:

This also fixes a potential problem with out-of-tree builds: Previously it
used sometimes srcdir[1] and sometimes not for this file,
possibly causing make to behave strangely when build out of tree.

Another bug of this kind is doc/Makefile.am using ../src/*.h instead
of $(srcdir)/../src/*.h or even better $(top_srcdir)/src/*.h.
(and as that is a file to be shipped in the source tarball, I'd put that
into the $(srcdir) [1]), i.e:

Another problem for out-of-tree working is version.texi. I think just
not generating that yourself and using the version generated by the
autotools solves this: Removing doc/version.texi.in, changing
configure.ac to not generate it, changing doc/gv.texi to use VERSION
instead of GVVER (and perhaps not using EDITION, as automake puts the
version in that too).

[1] which is already strange for generated, non-shipped files, and I do
not understand why it is done here (see also 2nd part of [2]).
It also breaks make distcheck.
