	Yes, it's me again, folks.  I've joined the mailing list, but please
    also email any answers to me as there may be a lag before I'm on it...

	I managed to compile temacs (thanks to Susan Hinrichs), but ran into
    another problem.  This was with either gcc-1.40 or gcc-2.1, on a Sequent
    Symmetry S81 running DYNIX V3.0.17.10.

	When running temacs, I got some strange results.  When temacs was
    built without optimisation, I got the following:

./temacs -batch -l ../epoch-lisp/inc-vers
Please set the environment variable TERM; see tset(1).
Make[1]: *** [epoch] Error 1

	even though TERM was set.  So I ran under gdb-4.4 and found that
    SIGTRAP was being generated, apparently straight away:

GDB 4.4, Copyright 1991 Free Software Foundation, Inc...
Gdb> run -batch -l ../epoch-lisp/inc-vers
Starting program: /v4/usr/src/epoch-4.0p0/src/temacs -batch -l ../epoch-lisp/inc-vers

Program received signal 5, Trace/BPT trap
_start () at crt0.c:225
gdb> 

	Where the arrow marks the guilty point (I also notice that it
    mentions Sequent):

_start ()
=>
/* On vax, nothing is pushed here  */
/* On sequent, bogus fp is pushed here  */
  start1 ();
}

	However, when compiled with optimisation option -O, I got a
    different outcome & got a little further.  This time the problem appears
    to be by giving memcpy a NULL pointer:

GDB 4.4, Copyright 1991 Free Software Foundation, Inc...
Gdb> run -batch -l ../epoch-lisp/inc-vers
Starting program: /v4/usr/src/epoch-4.0p0/src/temacs -batch -l ../epoch-lisp/inc-vers
Loading ../epoch-lisp/inc-vers...

	I am absolutely not a debugging hacker, and I have no idea what the
    problem here is.  It happens the same which ever version of gcc I use,
    so I'm not convinced that it is a compiler error, does anyone out there
    have any ideas?  Anybody managed to get epoch-4.0 up & running on a
    Sequent, and willing to lend a hand?

	Thanx in advance, Simon.
