I am hacking along on a 386 with XENIX 2.3, and having some small confusions.
Playing telephone tag with SCO support got boring. No blame, we're having a
contest over who is least available on the phone. If Saltz thinks this is a
helpful newsgroup, then how can I resist?
I am porting the underlying assembler language runtime for a Modula-2 system
from Sun-3 BSD (yes, a 68k) to XENIX/386, and can't seem to find some vital
pieces.
o Where is on_exit, and what should I do about it? Using adb, I can see _exit
going through a call chain, so how do I get on it? I just want to add one
meager teenie weenie little harmless entry.
o Where oh where is sigsetmask or its equivalent? I need to disable all
signals in a critical region and then reenable them just as they were.
o I have some numerical routines (Cody & Waite tests of MathLib0 functions)
which need to have all intermediate results rounded down to 64 and 32 bits.
I know how to set a 387's control register to do this, but how do I do it
when using the emulation?
Thanks.

PS: One or two foolish Modulans who want to be alpha test victims out there?
