Subject: [PATCH] RT #107353 says that we need to ignore SIGWINCH

The previous change only ignored WINCH if that
key existed in the %SIG hash. The Changes log
entry from 2.14-TRIAL noted that setting this
for systems that do not support WINCH could be
noisy. I'm guessing that's the old Mac OS X.

If we don't mind old things complaining, we can
always set it unless something got there first.

Or, let's add some notes about what concrete problems
come up when we always set it.
