I don't think this is make version dependent.  I can't reproduce the
issue today with make 4.1.  But I would have been using the same
version in August when I wrote that.

What more can I say?  Clearly the hyphenated variable gets passed to
the sub-make in most cases.  But it's not totally reliable because last
year it wasn't working for us.

I didn't write that, it's a standard message generated for bugs marked
as closed in a package changelog. :-)

This is the patch I applied to the package.
