flex problem

Sun Jan 7 15:31:00 GMT 2001

Dear All,
I recently installed the latest cygwin version
on WinNT 4.0; somehow all my Flex programs
started generating very strange output and
I wonder if could please help.
consider, e.g., this pretty straighforward Flex program:
/* to compile
 * bash-2.04$ flex l.lex && gcc -o l lex.yy.c
 *
 */
DIGIT [0-9]
ID [a-zA-Z[:punct:]]
%option noyywrap
%%
[ \t\n]+
({DIGIT})+ printf ("found digit\n");
({ID})+ printf ("found id\n");
. printf (":%s: length :%d: not found\n", yytext, yyleng);
%%
int main (int argc, char **argv)
{
 yyin = stdin;
 yylex ();
 return 0;
}
=====================================
then i get this pretty unexpected result:
bash-2.04$ ./l
hello
:h: length :1: not found
:e: length :1: not found
:l: length :1: not found
:l: length :1: not found
:o: length :1: not found

what could possibly go wrong here?
Thank you so much for any insights beforehand.
Best regards,
 Dmitry
