GNU Make already supports this feature (read the description of the -j 
switch in the make docs).  However, the DJGPP port doesn't support it 
because DOS doesn't allow multiple processes to be launched 
simultaneously.

We could make it work on Windows (by using the START command), but we'd 
need to solve the problem of communications between Make and its 
children, since START launches a separate Virtual Machine, and 
communications between VMs are tricky for DOS programs.

Make's sources are freely available--I'm sure patches to implement this 
would be greatly appreciated.
