Dont bother, I have nothing to do with the iBCS2 stuff anymore...

You still don't get it, try go out and buy some fairly fancy SCO app in
a shrink wrpped box, and the try to install it. Then you write down
ALL the things that went wrong, how to fix them, and then come
back here and tell me how much is missing before we have
"resonable" iBCS2/SCO emulation, fair ??

It had a problem in its socksys emulation which on of my "helpers"
ported from Linux. It should have been done differently, but well
it was a first shot. Besides this minimal bugfixes would have
done it. Due to me (& Sean) not having time to fix it, swallace
decided to take the NetBSD code and put that in instead of
fixing our own :( I guess one could take NetBSD's SVR4 code
and munge that into our tree as well (given the prober amount
of kernel bashing that would be nessesary).
Enough, this is starting to get rediculous...
