Are any deviations between these data structures still relevant
(or undesirable)?

The C AST and SmPL AST differs with respect to the enum type.
For an enumerator, the C AST is as follows:
Enum -> list of (name, (info, expression))
For the same, the SmPL AST is as follows:
EnumDef -> list of expression
While the SmPL parser does make sure that enumerators are
parsed as per C rules, the OCaml types for an enumerator themselves
mismatch, due to their organization. This causes bugs/mismatches for
cases where enums are in disjunctions.
Make the enumerator type of the SmPL AST closer to that of
the C AST.
