Follow-up Comment #33, bug #48643 (project make):
This fix turned out to be difficult. i'll be surprised if we don't miss
i wanted to bring to your attention a couple of leftovers.
One is that pat->is_explicit that is described in update 31.
For the other let's consider example 8.
%.tsk: %.o; touch $@
%.o: %.c; $(info $@)
Here, 'hello.o' is intermediate and 'hello.o' and 'hello.tsk' are not rebuild
when 'hello.o' is missing.
If we uncomment rule 'unrelated: hello.o', then 'hello.o' is explicit and
'hello.o' and 'hello.tsk' are rebuild when 'hello.o' is missing.
So, even though rule 'unrelated: hello.o' is unrelated and no longer
participates in overload resolution, presence of this rule affects make's
The tests in sv48643_exp_preqreq_is_not_interm_tests.diff all test that such
prerequisite explicitly mentioned on an unrelated rule is not intermediate.
i'd like to solicit your opinion on this.
