parallel make


Hi folks,
Currently our build environment uses parallel make (-j jobs option) on all
our unixes using gnu tools.  We use an older version of gnu tools on our
windows boxes.  The older make on the windows box does not do parallel
make (or at least correctly).  I want to upgrade to the latest cygwin to
see if parallel make works, but this will require significant changes to
our build engine, so I would like to confirm a few things if possible.

1. Does the -j jobs option work well on windows. (part b: does it work
with the MSVC (6/7) compiler (which probably doesn't make a difference
anyway)?
2. Has anyone done this in a very large project, and if so, do you have
any performance gain stats (which, I acknowledge, is tied to
processor-intensive makes and how many processors the machine has).

I realize that dos does not allow for threading so I don't know if this is
a cmd.exe-related issue or not (since cmd.exe is the parent shell, I
don't know if this affects the behavior).

thanks in advance --
