Solution to a Flex problem

Hi all,

I know this is a Bison and not a Flex venue, but just in case somebody
experiences the deletion of the letter "s" from their Bison output,
here's how I solved this symptom by changing my Flex program...

Originally my Flex program had the following:

\s*\n       {strcpy (yylval.y_char, yytext); return NL;  }

I was ignoring all whitespace at the end of every line. But my parser
deleted the letter "s" from the output. So I made the following change:

[ \t]*\n       {strcpy (yylval.y_char, yytext); return NL;  }

After the preceding change, all occurrences of "s" were passed through.

I hope this helps somebody.
