We can't just ignore #else to handle #if 0 .. #else <some code> #endif case. We can use PP_If to represent #else for this case, but it's misleading. And I'd prefer to have a closer model of the language syntax, if it comes at no cost. And we can also detect errors like #if ... #else .... #else. However I have no idea what to do with them ;)
