[net.sources] small change to cparen for SysV

bradn@hammer.UUCP (Brad Needham) (07/19/84)

I was overzealous in saying that cparen would build under SysV.
I believe that "rindex" is called "strrchr" under SysV.

I have removed the reference to "rindex" from cparen.  Here is a diff
listing:
======= the following changes apply to cparen.c =========

< 	char *rindex();

< 	if ((cmd = rindex(argv[0], '/'))) {
< 		cmd++;
< 	} else {

> 	for (cmd = (char *) 0, cp = argv[0]; *cp; ++cp) {
> 		if (*cp == '/') cmd = cp + 1;
> 	}
> 	if (!cmd) {
=========================================================
I apologize for overstating cparen's portability.  Thanks to Art Deacon
for pointing out the problem.
