I think the problem is that Hugs (up to and including Nov2002) had +W
set (to support the obsolete syntax for implicit parameters) if you set -98.
But now because that syntax is obsolete, MarshalUtils uses "with" as an
identifier.

The two sides of the problem (+W and MarshalUtils) are both in Hugs,
I think.

But what puzzles me is how hugs got the -98 option.  Maybe you can pass
-W the same way.
