Passing SIGWINCH on from a signal handler

[Charles Noren]

We wrote a signal handler to catch the SIGWINCH signal on
a Sun 3 with SunOS 4.0.3.
When we installed it, we found that signal() returns
a NULL the first time it is invoked.  
We were hoping to get the default signal handler for
SIGWINCH so we could use it to have the SunOS do its
normal window processing.
We were wondering if there is a way to pass the
signal on to the SunOS default signal handler after we
process the signal ourselves.
