/*
 * Bob Denny 28-Aug-82  Remove reference to FILE *lexin to
 *                                              eliminate dependency on standard I/O library. Only
 *                                              lexgetc() used it, and it's there now.
 *                                              Add EOF definition for standalone uses.
 *                                              Corrected comment for llnxtmax.
 *
 * Scott Guthery 20-Nov-83      Adapt for IBM PC & DeSmet C.  Removed
 *                                                      equivalence of yylval and lexval since
 *                                                      a multi-typed parser wants yylval to be
 *                                                      typed to be the union of the types (YYSTYPE).
