Decidedly missing.  POSIX doesn't require it.  Neither bash nor ksh
provides setvar as a builtin, either.  And what does setvar do anyways?
 Perhaps it is some alias or shell function that you have inherited from
startup files in one of your other shells, but I've never heard of a
'setvar' program.  So why bloat dash to include it?
