System: rn version 4.1
Bug #: 8
Priority: LOW
Subject: <sys/ioctl> not found on V7
Index: common.h
From: scw@cepu.UUCP (Stephen C. Woods)

Description:
	I [scw] have discovered a minor installation problem with V7 systems.
	Seems that there is no <sys/ioctl.h> on v7.

Repeat-By:
	Compile rn on a V7 system and see if it complains.

Cheap fix:
	Delete the include of <sys/ioctl.h>.

Complete fix:
	Making the following assumptions:

	(1) <sys/ioctl.h> is the set of collected arg2's for all the drivers.
	(2) systems without <sys/ioctl.h> have them in the correct places
	    (like sgtty.h>
	
	I hacked common.h to conditionally include <sys/ioctl.h> if IOCTL
	was defined (which it is not).  Worked like a charm. So appended to
	the message are the diffs from Configure and common.h to avoid the
	problem.

Fix:	From rn, say "| patch -d DIR", where DIR is your rn source directory.
	Outside of rn, say "cd DIR; patch <thisarticle".  If you don't have
	the patch program, apply the following by hand, or get patch.
