Details:
It appears that order-only prerequisites do not accumulate for pattern targets
when specified without a recipe. The test case should explain pretty clearly.
Here's the makefile:
% cat Makefile
.PHONY: all
all: foo.a bar.b
%.a: A B | C
@echo "making $@ from '$^ | $|'"
%.b: | C
%.b: A B
@echo "making $@ from '$^ | $|'"
And here's the sample run:
% mkdir -p A B C
% make
making foo.a from 'A B | C'
making bar.b from 'A B | '
