- consistently dealing with EOF and its effect on error recovery (bug 11444, #1)
- turning a simulated OO hierarchy of function pointers and typecasting into a real C++ class hierarchy
- correctly handling '\' everywhere, in all classes of tokens, as a layer before preprocessing itself
- conditionally handling '\n' in macro expansion input, depending on whether it is in a macro expression or not
- delete some unused "memory cleanup" code
