Ah, I was thinking in terms of the sort of macros in autoconf-archive,
but this would be a project-specific macro. (At least, I presume so,
as it would need to know about the targets in the project.) Hence I'm
thinking that this reservation doesn't apply so much to
autoconf-archive; please correct me if I'm wrong.

I suggest you mention this on address@hidden, as it does indeed
suggest that some elaboration, at least, of the GNU Coding Standards
is needed.
