This doesn't seem to be (currently) possible. I'm relying on the `enum_value` interface of `Cursor` to get the value, and that interface asserts `cursor.kind == CursorKind.ENUM_CONSTANT_DECL` which fails when I read this as C code (all variants have only a `CursorKind.PARM_DECL` and a `CursorKind.TYPE_REF` node in C mode)
