This patch fixes my botched attempted to patch deattack.c.
I created a bsd-cray.h file and cleaned up a few error cases
in bsd-cray.c. Fixed cray_setup call to pass uid and login name
in session.c and moved its call so that its called with root privs.
Its been tested on a irix, sun, aix, unicos(SV1) and unicosmk(T3E)
systems.
If you are building this on a T3E you may have to edit the Makefile
and edit out "-lrpc -lyp -lrpc". There a patch for sco that
incorrectly assume that you have a yp library if you
have a rpc library. I will submit a generic fix to this list
latter since it is generic problem.
I decided to go into a little more detail about the patches to
each module:
channels.c - Use a new subroutine from packet.c to get a singed
integer. The original bsd code use the fact
that you can set a 32bit unsigned int to a 32 bit
signed variable and recover the sign bit.
CRAY ints are 64 bit so the trick can't work.
configure.in - Add OSSH_PATH_ENTROPY_PROG(PROG_SAR, sar).
I missed this in the last patch. It is need for the
sar entry in ssh_prng_cmds.in
deattack.c - Modified to not depend on u_int16_t
being 16bit in size.
packet.c - Add new subroutine to return an explicit signed
integer.
scp.c - Modified to use alarm instead of setitimer.
Unicos does not support setitier.
serverloop.c - Modified sigchld_handler to only reset
SIGCLD if HAVE_SIGACTION is not set. This is the
only case its needs to be reset, the side effect
is it fixes the problem with a infinite signal loop
under unicos and unicosmk.
Modified waitpid to keep trying if it gets an EINTR,
this can happen due to job termination signal on unicos and
unicosmk.
session.c - Added unicos/unicosmk job termination signal handler.
Add TMPDIR envireent variable.
Add code to set up a unicos/unicosmk job and system
limits.
sshpty.c - Unicos/unicosk pty support.
In openbsd-compat directory:
bindresvport.c & - Code around the fact that the address of sin_port
rresvport.c. really is 64 bit aligned on a SV1.
bsd-cray.c - New - cray support routines.
bsd-cray.h - Cray support.

I suggest if you want to keep doing this to do #if !defined(HAVE_SIGACTION) && defined(_CRAY) because this could be valid on other platforms. mysignal drops back to signal() if sigaction() can not be found (most notiable NeXTStep).
