Something that I do sometimes is essentially:

   if  [ ! make -j all ]
   then
      make all
   fi

which works if you treat warnings as errors, which I believe you do.  If you
don't then you can lose your warnings.

I'm thinking about how output from this could be better.  The first thing
that comes to mind might cause  more file IO and make things worse,
though.   Hmmm...

Do all object files get created there initially or do some get created in
the source directory and then moved?
