These cause ambiguous compiler reference errors on some GCC versions. And, the errors seem right. But, newer versions of clang seem to resolve that ambiguity by also checking if the references to the types are also references to identical types. Per the chat with Jim, also added the Dl prefix to those types. No change in functionality. Just a rename of the types and removal of the now unnecessary typedefs.
