Subject: tty: winch_handler vs NO_SIGNAL
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1a2afd21d47eea6fd080bf8d1f7dc7f503149372;p=nethack

tty: winch_handler vs NO_SIGNAL

While testing something unrelated, I built with NO_SIGNAL
defined and winch_handler() caused an unused function warning.
