is not used since it consumes all preprocessor directives until it returns
a real token. Using the specific Lexer (i.e. CurLexer->Lex) makes it
possible to stop skipping after an #include or #pragma hdrstop. Previously
the skipping code was only handling CurLexer, now all will be handled
correctly.
