Various makefile changes
 2016-03-10 10:18:06 +10:00
Warren Toomey 2880d1b2e4 I've made a start on a mkfs tool for PDP-7 Unix. So far I have the routines 
to build the filesystem, but they are not tested. I need to add code to
parse the "proto" file, whose syntax is based on the 6th Edition proto file.
I also need to dump out the filesystem image.
