On (info "(make) Automatic Variables")
please mention which of
M:/dev/null /dev/zero
: $?
: $+
: $^
: $|
are guaranteed to preserve the order. I.e.,
/dev/null /dev/zero not
/dev/zero /dev/null.
and which all bets are off.
Also maybe when people read about
(Info-index "order-only prerequisites")
mention also there is also a second kind of order,
the kind I mention above.
