Here's a test case reduced from a much larger build system demonstrating a
behavioural change between 4.3 and 4.4 which caught me by surprise:
.SECONDARY:
.PHONY: force
-include test.foo
%.foo: force
touch -a $@
%.x: %.foo
touch $@
test: test.x
touch $@
*with 4.3*
*%* ls
Makefile
*%* make
touch -a test.foo
touch -a test.foo
touch test.x
touch test
*%* ls
Makefile test test.foo test.x
*%* make
touch -a test.foo
make: 'test' is up to date.
*with 4.4*
*%* ls
Makefile
*%* make
touch -a test.foo
touch -a test.foo
touch test.x
touch test
*%* ls
Makefile test test.foo test.x
*%* make
touch -a test.foo
touch test.x
touch test
*with --trace*
*%* ls
Makefile test test.foo test.x
*%* make --trace
touch -a test.foo
Makefile:7: update target 'test.x' due to: target does not exist
touch test.x
Makefile:9: update target 'test' due to: test.x
touch test
I've reported this a bug because:
* test.x exists but make 4.4 says it doesn't
* test.foo is older than test.x therefore test.x does not need to be updated
