_______________________________________________________
Details:
The $^ should contain all the prerequisites that are newer than the target,
including missing prerequisites.
However, the '.SECONDARY' special target is present,
the missing prerequisites are not included in the ^$.
[Test code]
foo: bar baz
@echo newer prerequisites are: $?
bar:
.SECONDARY:
[Result]
$ touch foo
$ touch baz
$ make
newer prerequisites are: baz
The 'baz' is correctly contained in $^ since it is newer than 'foo'.
We expect 'bar' in $^ as well because it does not exist. However, this
behavior is changed by the presence of .SECONDARY.
If you delete the '.SECONDARY:' line, the result is what we expect:
$ make
newer prerequisites are: bar baz
