How much modifications would you need?
I doubt removing copyright notice, changing the case on comments and
changing line break would suffice.
That seems what was done on some of the original string library header files.
(see ftp.nvg.ntnu.no:/pub/vms/free-vms/str.tar-gz).
Compare those header-files with the ones from VMS itself.

I have fixed that by removing comments and reindenting, and put together
what I am using at ftp.nvg.ntnu.no:/pub/vms/freevms/freevms.tgz
(It follows the VMS source structure, but not everything is in its right place)

New functionality is under way.
I have seen no concrete plans for modifying existing kernel functionality,
just loose suggestions.
We might need some basic datastructures and libraries first, like
parts of LBR, LIB, STARLET, LIBRTL.
(Otherwise, we may have to take some breaks to make them when we need them)

Anyone who can do some of this?
It is just coding the header-files anew (write comments anew too) and
coding some routines according to a specification, and can probably be
done under any Unix.
Just send a mail here and say it, so we are not having duplicate work.

Compromises, compromises.
We should still have 4 rings, or at least pretend to.
In those cases, maybe we should let U take over the S, and K take over the E
functionalities?
Maybe we should just worry about the PC right now. (With its registers,
interrupts etc)
