I doubt it, because the idea is to create a name space, avoiding name  
conflicts in case one uses more than one parser. Instead, define a  
new function calling it, or if that is not possible, use the C/C++  
preprocessor, something like:
#define yylex my_yy
... /* Changes yylex -> my_yy here */
#undef yylex
