PROBLEM:  (QAR57670)                 (Patch ID: OSF425-400455)
********
This patch fixes a problem with the lex command. Programs built with
lex may exhibit various problems which only occur after the following warning:

        Maximum token length exceeded

To reproduce the problem, use the following lex specification:

%{
#define NUMBER 400
#define COMMENT 401
#define TEXT 402
#define COMMAND 403
#if defined (YYLMAX)
#undef YYLMAX
#define YYLMAX 20
#endif
%}
%%
[ \t]+  ;
[0-9]+                  |
[0-9]+\.[0-9]\+ |
\.[0-9]+        { return NUMBER; }
#*                      { return COMMENT; }
\.[^\"\n]*\"    { return TEXT; }
[a-zA-Z][a-zA-Z0-9]+    { return COMMAND; }
\n                                              { return '\n'; }
%%
#include <stdio.h>

int main(int argc, char *argv[])
{
        int val;

        while(val = yylex()) switch(val) {
                case NUMBER:
                        printf("NUMBER\n");
                        break;

                case COMMENT:
                        printf("COMMENT\n");
                        break;

                case TEXT:
                        printf("TEXT\n");
                        break;

                case COMMAND:
                        printf("COMMAND\n");
                        break;

                case '\n':
                        printf("RETURN\n");
                        break;

                default:
                        printf("Unknown:%d\n", val);
        }
        return 0;
}
lex lexer.l
cc lex.yy.c -o lexer

To execute the test, type in any character sequence. If you type a
character sequence greater than 20, you will receive the following message:

          Maximum token length exceeded
