I have just compiled version 3.58 of the GNU make program on an apollo.
This version of 'make', which by the way has the best documentation of
the 'make' tool I have ever read, supports 

	1) a '-j' option. If you do

	   make -j 5

	   5 parallell compilations will be launched when make starts up.
	   So if you have a product which contain 10 files, it will launch
	   5 compilations immediately and then do the rest of the files one
	   after the other. '-j' is short for job slots.

	2) there also seems to be support for some kind of networking 
	   facility. In the Makefile of 'make' one can read:

		# If there are remote execution facilities defined,
		# enable them with switches here (see remote-*.c).
		REMOTE =

So if you combine 1) and 2) above I suppose you get just what you 
are looking for. 

I have not yet figured out how to use 2) above, anyone else ?
