System: NetBSD zen.quick.com.au 1.3.2 NetBSD 1.3.2 (ZEN-PUC) #2: Sun Oct 18 18:37:34 EST 1998 sjg@zen.quick.com.au:/u3/NetBSD/1.3.2/src/sys/arch/i386/compile/ZEN-PUC i386


>Description:
	
NetBSD's getopt(3) treats --foo the same as --
Eg:

$ getopt "vp:-:" -v -p one --unlink a n c
 -v -p one -- a n c

This is compatible with the behaviour on SunOS 4.X, but SunOS 5.X
does the right thing:

: sjg:54; uname -a
SunOS frodo 4.1.4 2 sun4m
: sjg:55; getopt "vp:-:" -v -p one --unlink a n c
-v -p one -- a n c 

: sjg:2; uname -a
SunOS zen.cdn.telstra.com.au 5.6 Generic_105181-06 sun4u sparc SUNW,Ultra-60
: sjg:3; getopt "vp:-:" -v -p one --unlink a n c
-v -p one -- unlink -- a n c 
: sjg:4; getopt "vp:-:" -v -p one -- --unlink a n c
-v -p one -- --unlink a n c 

Not tossing the chars after "--" allows progams to support options like
--unlink without having to resort to GNU's getopt.
