[bug #27047] Difficulties defining prerequisites for pattern targets.

[Robert L Walton]

Follow-up Comment #2, bug #27047 (project make):

Fails in the sense that applying `make' to

++
all:    test1001.out

foo:
        @echo making foo

test1%.out:     TEST=foo

test%.out:      ${TEST}
        @echo making test$*.out with TEST=${TEST}
--

produces 

+
making test1001.out with TEST=foo
--

when I would like it to produce


+
making foo
making test1001.out with TEST=foo
--

The pattern specific variable is not substituted in the first
${TEST}.

Pattern specific variables get substituted in the commands but NOT the
prerequisites, apparently.

The use of pattern targets without commands to cancel previous pattern target
rules is unfortunate, since it conflicts with the common non-pattern use of
adding prerequisites.  Too bad.  Worse, the cancel usage is obscure and the
failure of the prerequisite use is confusing to debug.
