Follow-up Comment #34, bug #48643 (project make):

I didn't fully grasp the impact of the issue you raised in comment #31.  Do
you mean that if I apply the test patch mentioned there, some of those tests
would fail?  I will try to look at this more this evening.

Regarding your question in comment #33, the current behavior is correct.  It
has always been the case that any mention of a target in the makefile is
sufficient to remove the "intermediate-ness" of a file.  In fact, this is a
very common, and very often recommended, way to remove intermediate status of
a file; we suggest adding a separate target like:


build-intermediates: <list of intermediate files>


and even if that target is never invoked, it's sufficient to mark those
targets as "mentioned in" the makefile and thus remove their intermediate
status.

Changing this would break a lot of things.
