Follow-up Comment #4, bug #60736 (project make):
The reason the exception exists is so that you can specify an extra target
globally. You are testing a target-specific variable version, but if you set
this globally:
.EXTRA_PREREQS = foo
bar foo: ; @echo $@
This will always generate a warning, if this patch is applied. This makes the
whole concept of setting this variable globally essentially not useful: no one
wants to have warnings like this always generated.
I understand that not having this warning can mean that a typo can go
unnoticed but I'm not sure I agree that forcing this warning on all users of
the global assignment is a better alternative.
