The Unix stuff that runs on top of Mach (3.0 that is - Mach 2.5 and earlier is deeply embedded in the 4.3BSD kernel and is almost certainly not what you're thinking of) makes extensive use of Unix source, as well as source from hardware vendors for drivers, math libraries, boot code, etc. For rewrites of existing software you're better off looking to CSRG and the FSF. -- Software longa, hardware brevis Melinda Shore - Cornell Information Technologies - shore@theory.tn.cornell.edu
