Subject: Re: [klibc] dash fix for job control off warning

There seems to be a problem with the new version of dash
with job control off.  I can't tell if it is just a warning or is a
manifest bug.

usr/dash/trap.c: In function `exitshell':
usr/dash/trap.c:376: warning: suggest braces around empty body in an `if'
statement

The solution is simple:

--- a/usr/dash/jobs.h
+++ b/usr/dash/jobs.h
@@ -105,5 +105,5 @@ int waitforjob(struct job *);
 int stoppedjobs(void);

 #if ! JOBS
-#define setjobctl(on)  /* do nothing */
+#define setjobctl(on) ((void)(on))     /* do nothing */
 #endif

... to keep the code syntactically valid even when setjobctl() is used
as the body of an if statement.
