$ cat Makefile
V=
t1: t2
t1: V+=v1
t2: V+=v2
%:
@echo target=$@ V=$(V)
$ make t1
target=t2 V=v1 v2
target=t1 V=v1
$ make t2
target=t2 V=v2
$ make t2 t1
target=t2 V=v2
target=t1 V=v1
$ make t1 t2
target=t2 V=v1 v2
target=t1 V=v1
make: `t2' is up to date.
i expected V to be consistently v2 for target t2,
the fact that t2 is a dependency of t1 should not
change the variable setting for t2 because that
makes the result unpredictable
