>Description:

If you want make to build multiple targets, you can pass multiple
targets on the command line:

   % make foo bar

but if you need them to happen serially, you're stuck:

   % make -j8 foo .WAIT bar
   make: make: don't know how to make .WAIT. Stop

(also the error message shouldn't say "make:" twice...)

>How-To-Repeat:

>Fix:
Not sure why this doesn't already work; I suppose targets on the
command line pass through different processing from targets on the RHS
of a rule, but there probably isn't any good reason for that.

 That reloads the makefile... but I guess you aren't stuck per se.
 Anyway, there's no reason rules on the command line shouldn't accept
 .WAIT besides "the code sucks" :-/
