Not entirely true: the MS-Windows port does support parallel
execution, but it does not support the "job server" method.
Therefore, Make invokes sub-Make's with the "-j 1" switch.

To work around, invoke the sub-Make's with an explicit "-j N" switch
(you will need to figure out the argument N yourself).

Alternatively, volunteer to make the job server work on Windows ;-)
