/* A lexical scanner header generated by flex */
/* MODIFIED FOR C++ CLASS BY Alain Coetmeur: coetmeur(at)icdc.fr */
/* Note that (at) mean the 'at' symbol that I cannot write */
/* because it is expanded to the class name */
/* made at Informatique-CDC, Research&development department */
/* company from the Caisse Des Depots et Consignations */
/* Modified to support cheap/builtin linecount, 1994/10/24.
** by Gregor Buehler 100440.2470(at)compuserve.com
** Changes: included YY_(at)_LINENO definitions like for YY_(at)_LENG
** included related member (C++) or static/extern (C) variables
