patches for UnixWare v2.x pty (misc.c,configure.in)

[tom at avatar.itc.nrcs.usda.gov]

I have attached two patches to the current source code. The first
addresses the pty problems with UnixWare 2.x with connecting with
SSH2. It sets the sigaction to SA_RESTART. This fixes UnixWare v2.x,
but haven't heard any feedback as to effects on other OS'.

The first patch is against misc.c.

The second patch adds a section "*-*-sysv4.2uw2*" to configure to
set the TEST_MINUS_S_SH shell and define USE_PIPES.

I suspect these same fixes apply to UnixWare 7.x, but I don't have
access to that build platform, or I would include them in the config
as well.

Let me know whether these can be applied against the current source
tree.

Thank you,
