I can't really say that I am fond of this approach - at all. We already
store the linkage name as well as the natural name. Can't you use that
in the language-specific lookup routines to make the search case
insensitive?

There is also something I'm confused about: If Pascal is *not* case-
sensitive, why make the debugger optionally case-sensitive? Why not
always have a case-insensitive interpreter?  You aluded that there were
some reasons...
