System: NetBSD nool 1.4R NetBSD 1.4R (NOOL-$Revision: 1.6 $) #0: Thu Feb 3 08:50:33 MST 2000 jbernard@nool:/home/tmp/compile/sys/arch/i386/compile/NOOL i386

	The script .../share/examples/emul/svr4/etc/SVR4_MAKEDEV contains
	syntax errors and so cannot be used to create devices for svr4
	emulation without being fixed.  (Well, yes, it *is* an example,
	but it would be nicer if it worked, and compat_svr4(8) claims that
	it can and should be used as is.)

	Copy the script to /emul/svr4/dev (or wherever) and say
	"sh SVR4_MAKEDEV".  The error message is:

	  ./SVR4_MAKEDEV: 156: Syntax error: ")" unexpected (expecting ";;")

	The problem is a case statement in the "wabi" section--it was written
	using c-style "fall-through" syntax instead of shell-style "alternative
	patterns" syntax.  The problem was introduced in revision 1.6, way
	back in April (IIRC) of 1999; I guess nobody has used it since then.
	Here's one way to fix it that, I believe, matches the intent of the
	changes introduced in 1.6:
