[bug #45311] makes only one of two dependencies that depend on the same subdir-pattern rule

[David Boyce]

Follow-up Comment #2, bug #45311 (project make):

I think the confusion here has to do with the value of address@hidden One might
reasonably expect, in a multi-target pattern rule, that $@ would be the list
of all matching out-of-date targets but in fact, according to the
documentation:

"In a pattern rule that has multiple targets (see Introduction to Pattern
Rules), address@hidden is the name of whichever target caused the rule’s recipe 
to
be run."

Which is a bit unclear wrt the case where neither target exists, but does
imply strongly that $@ will refer to just one target.
