Ack.

>From earlier (uinrelated) discussion, I think we have other cases
where the "minimum recommended" may not be true (even gcc - it might
be true on some architectures with simple configs, but we've had
long-standing known issues with some more complex configurations where
the "minimum" gcc version simply didn't cut it and could generate
incorrect code).

For the GNU make case, you make a strong case of "it hasn't worked for
a while already and nobody even noticed".
