From 9ea1bae7e4d8ac4e6b0e7d7f615ab95305462cf0 Mon Sep 17 00:00:00 2001
From: Chris Hanson <org/chris-hanson/cph>
Date: Mon, 22 Nov 1993 22:45:43 +0000
Subject: [PATCH] Fix conditionalization of HAVE_FTRUNCATE -- it was broken for
 those operating systems that were both POSIX and BSD.  Also, define
 TIOCSIGSEND on several operating systems that support it under a different,
 undocumented name: TIOCSIG.
