We are pulling in as many files as needed from Original NetBSD tree
here.  We minimize work by preserving directory hierarchy and
as much of the contents as possible.   This is obviously a tricky
business, but better than recreating everything.

The directory under here xxx/include where xxx is machine name 
should be symbolically linked to ../xxx.
For example sparc/include is symlinked to ../machine before
build can successfully happen.

The ../ directory (top of our tree) must have this machine directory
to build evertyhing.  Of course on Windows PC's you can't have
symlinks, so you have to copy the hole directory.  E.g. Directory
i386/include here gets copied to ../machine.

Other directories under each machine architecture can remain here.

Additionally, one has to be very careful around here :-)
