>Description:
Considering the following `Makefile.test':

all: a b

a: .PHONY
        @echo after

b: .PHONY
        @echo before

.ORDER: b a

Triggers the following default behavior:

% make -f Makefile.test
after
before

While when the invoked with `-j', the .ORDER directive is respected.

% make -j 2 -f Makefile.test
before
after

Removing the .ORDER directive trigger the default behavior.

This could be fixed by making `a' depend on `b', but this may not be possible when dealing with dynamically generated rules.
