Details:

I’ve found a use case in which a chain of prerequisite targets appears to
ignore the private modifier on a pattern specific variable definition. This
occurs in gnu make 3.82. Please find a simple example of this use case below.
This seems like a bug.

This looks like a bug of a similar type to bug #32872, however that bug is
with target specific variables, not what Paul referred to in other bugs as
pattern specific variables.

Make 3.82 behavior:

$make-3.82 -f Makefile debug
build: IMMEDIATE[-debug -implicit] DEFERRED[-debug -implicit]
all: IMMEDIATE[-debug -implicit] DEFERRED[-debug -implicit]
debug: IMMEDIATE[-debug] DEFERRED[-debug]

$make-3.82 -f Makefile all  
build: IMMEDIATE[] DEFERRED[]
all: IMMEDIATE[-implicit] DEFERRED[-implicit]

Expected Behavior:

As I understand it the -implicit string should never occur outside the
evaluation of the all target. E.G. The output of the debug target evaluation
above should be, with the non-private –debug modification taking effect, and
the private –implicit modification not taking effect outside the all
target.

$make-3.82 -f Makefile debug
build: IMMEDIATE[-debug] DEFERRED[-debug]
all: IMMEDIATE[-debug -implicit] DEFERRED[-debug -implicit]
debug: IMMEDIATE[-debug] DEFERRED[-debug]
