	Help!, I'm trying to get version 18.52 of GNU Emacs to
compile, link and run cleanly on our Harris HCX-9 running HCX-UX.....
a duel universe system. The idea is to achieve compatibility with both
the AT&T SYSV.2 and 4.2BSD versions of Unix.  The att universe creates
a compilation environment that should appear to be AT&T SYSV.2, and
the ucb universe creates a compilation environment that should appear
to be 4.2BSD. I am using the ucb universe to compile Emacs.

The problem is an undefined external refrence:  croak  
in the distribution file:  sysdep.c

croak is used only in these two calls (lines 638 - 648) after the C
preprocessor has its way
 
request_sigio ()
{
  croak ("request_sigio");
}
 
unrequest_sigio ()
{
  croak ("unrequest_sigio");
}

The problem is that neither STRIDE or FASYNC is defined. I don't know
what either means so I don't know if I should set them or if this is a
bug. If I can track this down I can provide s- and m- files and some
diffs for the HCX-? Systems.

				Thanks, Chuck
