I have been using make -j 4 .... in cygwin for 10 years on the 4 
hyperthread Pentium D.  Is that not a solution for you? I never expected 
a performance improvement beyond that number of threads.  If you don't 
mean make which comes with cygwin, I don't see how you will get help 
without explaining your question.
