I think this has been discussed before, but I couldn't find it in the
archives: do we still want to support really old bison versions (i.e.
those that need BISON_HAIRY and BISON_SIMPLE to be set) in 2.04?

The current bison (1.33) is once again stable, and thanks to Juan Manuel
should work out of the box (I still need to run a few tests to ensure
it will also configure out-of-the-box on plain DOS, but for that I need
a decent SFN environment set up first; VMWare is not cutting it).  It
will default to $prefix/share/bison/ as directory for the two skeletons,
and thanks to /dev/env/DJDIR, that should now be correct on all DJGPP
machines.

I believe 2.04 should ditch the variables altogether (and bison's README
should probably tell users to remove old skeletons from $DJDIR/lib to
avoid problems).
