Re: [Automake-NG] Can we require GNU make >= 3.81? (make memoization doesn't work with GNU make 3.80)

No objections from me, of course.  3.81 is widely available.

Actually, if automake-ng were to require 3.82, it would certainly
help have 3.82 be more wide spread.  If you were to require 3.82,
then I would support you.  You can count on me to defend the
choice of ONESHELL too.

BTW, if we can't require it, then at least I'd like Automake-ng
to be compliant.  I would feel safer if the test-suite could
also be run under ONESHELL.  And if there are accommodations
to make to be compliant, then having an automake-ng option
for ONESHELL should not too expensive to pay.  And I'd be
quite happy to know what the impact one performances are
(including on Windows machines where fork is known to be
very expensive).
