Well, to reveal the truth, the new values (that work, that is, I think
I can tweak them further) are
Ptab = 0x7fff5000, (could possibly be 0x7fffe000)
Execstk = 0x7f001000, (not sure about this one)
(thank you, Charles, you put me on the right track), and now I have
a version of Alef for 3rd Edition Plan 9 that (apparently) compiles
and executes programs on my i386 PC. Anyone got something easier than
the test/ programs. I tried sieve, pstest and tstbio with seeming
success, I'm not sure what test should produce and I have not tried
anything else.
I haven't yet tackled the graphic libraries (libg.a and libframe.a), I
suspect I won't get that right alone, but I'll give it a good try.
Only too happy to feed back the changed sources to Bell Labs, and do
whatever necessary to keep them current.
I have no idea what other changes to the 2ed libraries I may have
neglected, and so on; feel free to push me in the right direction.
