That's good news (I think :-P).  I checked the 2000-05-05 snapshot of
OSKit into our CVS repository for further review.  I know Ron and I agree
that we want to work on gnumach at this stage, but I may also work on
adapting our work to OSKit at the same time.  I've already started fixing
up the ELF stuff in OSKit for Elf64...

Hehehe...it was just hard to believe for me :-P  Then again, I've been
using Alphas since BLADE was around, so I've lived in a 64-bit world for
awhile and always have that eye for portability and ease.

True.  In reality, looking through OSKit sources (especially the ARM
support) has helped me get a perspective on things a bit better.  Gnumach
can get hard to relate to sometimes since there isn't really any support
for other architectures to base work on.

Probably, and it's understandable.  I know I don't mind supporting my old
projects, but it's not on the top of my priority list to do so.

I need to subscribe and I'll check into it.

Well, I needed the headers fixed up or else we'd be dealing with 64-bit
issues immediately.  I intend on starting real work tonight or Thursday
(unless we get a hurricane this week...living in Miami sucks).
