This one-line change to relay/control.c will avoid creating $NEWSARTS/fake:

Failure of the exploder regression test is a known problem (some tars
don't make empty directories).  The fix should be as follows:

#! /bin/sh
cd explode/regress
mkdir master/out.going master/out.going/bar master/out.going/baz 2>/dev/null
mkdir master/out.going/foo out/out.going out/out.going/bar 2>/dev/null
mkdir out/out.going/baz out/out.going/foo 2>/dev/null
>>master/out.going/bar/togo
>>master/out.going/baz/togo
>>master/out.going/foo/togo
>>out/out.going/bar/togo
>>out/out.going/baz/togo
>>out/out.going/foo/togo


Empty Expires: headers (such as produced by Pnews) are not just quietly
deleted by inews.  The fix is to misc/canonhdr.c:

122c122,123
< 		    STREQN(nhdr, expiresnm, STRLEN(expiresnm))) {
---
> 		    STREQN(nhdr, expiresnm, STRLEN(expiresnm)) &&
> 		    nonnull(nhdr+STRLEN(expiresnm))) {
139a141,149
> }
> 
> int
> nonnull(s)
> char *s;
> {
> 	register char *nwp = skipsp(s);
> 
> 	return *nwp != '\n' && *nwp != '\0';


Sites with the SysV tr need to execute this before building C News:

rm inject/stripinvis


The UCB passwd file GCOS field "&" hack in inject/fullname.c contains a
bug; here's the fix:

50c50
< 		(void) strcat(newgcos, cap);
---
> 		(void) strcpy(newgcos + (delim - gcos), cap);


inject/pnews refers to a command named "ersh", which we didn't ship.
Change "ersh" to "rsh" for now.


relay/ctl/alternate is obsolete and interferes with installation; the fix is

rm -rf relay/ctl/alternate


The clever dicks on the POSIX committees gratuitously changed the return
types of a bunch of "standard" functions, in the grand ANSI C tradition
("preserve existing correct code"?  just say no).  A particularly
annoying one is that umask now returns a mode_t, not an int.  If you
can't compile C News because your system has been posixiated, the quick
fix is:

(echo 'g/umask/d'; echo w) | ed h/libc.h


inject/actflag quits early if it encounters a group that is not known
locally.  This diff to inject/actflag.c fixes it:

77,79c77
< 		if (actent == NULL)		/* group not known locally? */
< 			continue;		/* keep trying */
< 
---
> 		if (actent != NULL) {		/* group known locally? */
113c111
< 
---
> 		}


Don't use our faster stdio on SunOS 4.1 and later releases.  stdiock has
been updated to catch this latest incompatibility.
