[M3devel] make_dir failure

[Jay]

It looks ok to me.
What happens if you create /usr/local/cm3/bin and /tmp/cm3/usr/local/cm3/bin?
Unix is imho bogusly finicky and doesn't like foo/../bar unless foo exists.
Windows parses out the .. without checking if foo exists, leaving this sort of construct more useful.
The Modula-3/Quake code I think never smushes out the ".." here, but making it do so is very reasonable.
 
 
This is part of how I avoid cminstall and just having one cm3.cfg -- all the paths are computed from the path of cm3/cm3.cfg. Probably defaulting them in the Modula-3 code instead of requiring them be set by Quake would be good, as part of a larger goal of more Modula-3 and less Quake. Quake coudl still override them if necessary.
