Thanks again for this.

There are still a few things that don't work in the Automake support for
vala, as uncovered by the rest of this discussion.  However, all issues
found so far can arguably be construed as limitations.  The current set
of changes looks like it's quite unlikely to cause regressions for
anyone not using vala, nor for any non-vala features when using vala.
We can fix things incrementally, but we don't need to keep vala support
out of the main Automake for that.

As a minor technical detail, I'm trying to avoid git cherry-picks
starting from post-1.10 Automake, thus instead of your rebase, I
have gone ahead and

- merged part of the next branch into the mh-vala-support branch (so
  your patch would apply cleanly),
- applied your patch, then
- applied the patch below to the mh-vala-support branch, which fixes a
  couple of harmless typos but also declares vala support as initial,
- then merged the mh-vala-support into the current next branch.

It is a bit confusing that ChangeLog and "git log" show things in
different order, but that is more or less unavoidable when using several
parallel lines of development.  I have verified that the result tree of
the above looks identical to your patch series.

I have now pushed the result.  I will soon merge next into master, too.

Cheers,
Ralf

    More minor fixups to vala support.
    
    * automake.in (lang_vala_finish_target): Fix typo in comment.
    * doc/automake.texi (Vala Support): Fix typo.  Declare vala
    support as "initial".
    * NEWS: Likewise, declare vala support as "initial".
