Follow-up Comment #1, bug #21198 (project make):
In which order do you think the prerequisites should be built? And why?
If C should be built before D, for example, then we have to tell make that D
depends on C. Mentioning D after C in a list of prerequisites is not
sufficient. Mentioning D on a later line than C is not sufficient. We have
to say that D : C, or that D : X where X : C, or D : X where X : Y and Y : C,
or similar.
The ordering is otherwise up to make and may (and, as you've seen, does) vary
from release to release and even from invocation to invocation. With -j, C
and D can even be built in parallel.
