says it pretends to make.
This bug was apparently harmless except for normal cases involving
.ORDER statements when it made debugging of -jN using -n very
confusing. E.g., for:
.ORDER: beforedepend .depend
depend: beforedepend .depend
where beforedepend depends on something so that it is not initially
up to date, `make [-n] -j2 depend' causes `make' to wait for itself
to make beforedepend. This works fine without -n. The job to make
beforedepend has normally been started, and beforedepend is marked
as made when the job completes. However, with -n, the pseudo-job
for making beforedepend has normally completed, and in any case
there was no chance of beforedepend being marked as made. `make'
actually exited almost immediately with status 0 instead of waiting
forever.
