Sure, I realize that.  But that only helps developers.  I was thinking
about users of open source software, building it on larger machines with
-jN and wanted to get "clean" output when it fails.  That's my
situation: I have archived vanilla tarballs downloaded directly from the
upstream sites, and I have a makefile that does all that's necessary
(unpack them, configure, build, install, etc.)

I certainly don't want to have to go modify the Makefile.am /
Makefile.in files to get this feature enabled.

Also apropos of nothing, I don't like this name :-).  Maybe .OUTPUTSYNC
or something would be better?  PARALLELSYNC doesn't help understand what
the feature does.
