The behavior decumented in POSIX seems to me like the "natural"
behavior as I believe that an impartial observer would expect the
documented behavior for the top level make to also apply to submakes.
Do you know of any specific makefile on ON that would fail if the
behavior would be implemented?
I personally believe that this is a change that is important
because it affects behavior and usability. Just in contrast to
changing build support script to use ksh93 syntax ;-)

Ah, it may be that I did know this already as I had in mind that
this feature did work already somewhere around 2006.

Thank you!
