netnews under Eunice - bug fix

[libes at nbs-amrf.UUCP]

This is in response to t4test!chip's complaint about multiple postings not
working under Eunice due to link().  This was exactly the behavior on our
system (running B 2.10 Beta 3/9/83).  I'm not that concerned about disk
space so I changed the link to a cp.  Works fine.

Forgive me for posting this to multiple newsgroups (one at a time!).
Obviously the people who have this bug will miss it if I didn't do this.

Here is the change to inews.c:

522a523,524
> 		struct stat dummy;
> 
524,529c526,540
< 		if (link(ARTICLE, bfr) == 0) break;
< 		e = errno;	/* keep log from clobbering it */
< 		fprintf(stderr, "Cannot install article as %s\n", bfr);
< 		log("Cannot install article as %s", bfr);
< 		if (e != EEXIST) {
< 			log("Link into %s failed, errno %d, check dir permissions.", bfr, e);
---
> 		if (stat(bfr,&dummy) == -1) {
> #ifdef VMS
> 			char system_arg[BUFSIZ];
> 
> 			/* copy since VMS doesn't do links - DEL */
> 			sprintf(system_arg,"/bin/cp %s %s",ARTICLE,bfr);
> 			if (0 == (e = system(system_arg))) break;
> #else
> 			if (link(ARTICLE, bfr) == 0) break;
> 			e = errno; /* keep log from clobbering it */
> #endif VMS
> 			fprintf(stderr, "Cannot install article as %s\n", bfr);
> 			log("Cannot install article as %s", bfr);
> 			log("Link into %s failed, err=%d, check dir perm",
> 				bfr, e);
