Look, as far as I can see in the git repository, this syncout primitive
is more or less what I was looking for. Especially if, as Gary suggests
in a separate e-mail, it can be extended to even configure the syncline
format.

However unfortunately what I have to do with m4 will be relevant only
this year and possibly at the beginning of 2010. My interest in this
does not (yet) expand further in time, and meanwhile I have to share
this work with people working on environments when non-existing versions
of m4 cannot be installed.

So as sexy as it looks like, until this features makes it through m4 1.5
or 1.6, I can't afford to even consider it.

Cheers,
