Details:
i have a feeling this is already known, and maybe accepted, behavior, but it
seems wrong, non-intuitive, to me.
if i have a dependency chain like
++
b1: a1
touch b1
touch c1
c1: b1
d1: c1
touch d1
--
then, if b1 needs to be re-made, d1 will *not* be remade, even though c1's
prerequisite b1 is out of date.
if i change to 'c1: b1;', it works.
i find the behavior surprising, and i would think worthy of changing. (i'm
guessing this is an optimization?)
with the attached Makefile, a 'make test' will show failure (or, success,
should it succeed).
