Doug -- the question isn't whether it is reasonable, but rather whether
there is any part of the code that was possibly derived. Surely Kent's
part of SUnit can be licensed however he wants, but the subsequent code
developed in Squeak is probably licensable only in Squeak-L. Likewise
SM and SMPL.
If SmaCC is unchanged from the original code, I agree that a dual
license is possible. To the extent there is any Squeak-specific
modifications, there are two approaches: (1) to single license the
whole under a conjunctive (not disjunctive) Squeak-L with the
additional notice or other provisions of MIT; or (2) to distribute
SmaCC under MIT, and a separately developed changeset to make it work
in Squeak under Squeak-L. (2) is probably the most straightforward
