I understand your concern, but I don't know that we can wait for
GCC/autoconf/automake to have new releases with this support before we
release 3.81.  It's possible there will be such releases, but I don't
want to predicate the 3.81 release on it.


This is a hard problem, because any change that these tools make to
support this new feature will automatically force the resulting output
to be GNU make-specific: it will no longer work with any other version
of make.  I don't know if that's acceptable to them (or maybe that's how
it works already?)


I did post a question on the auto* mailing lists back in March when you
brought this up, discussing the new feature and the implications for
these tools, but I received no response from anyone so I don't know what
to make of that.
