 * Due to the way that flex/bison works, the symbols were being added
   to the scanner after additional lines are parsed.
 * If these lines are #line directives, then scanner->current_filename
   can change between when the symbol is parsed and when it's added.
 * Change so that symbol gets filename when parsing rather than when
   being added to the scanner.
