Well, shoot. 

That leaves make(1) for doing things in parallel on S10, then. 
Similarly, one could write out a temporary makefile then invoke make -j.
 Wait, that's part of the PWB on Sol10, never mind :-(. 

To my surprise, the -P (parallel) option is not part of any POSIX or
X/Open or SUS specification that I can find right now, but it's
sufficiently widespread that (as long as you don't need to run Solaris
10) I'm still calling that "portable".  -Ish.
