Which package is required to build Lex&Yacc in cygwin [gcc -ll]

[Krisakorn Rerkrai]

Hi all,
      I tried to make my parser under Cygwin environment. It works well 
under the Linux but I have to do it also in Cygwin. It cannot find gcc 
-ll command:
     This is my result:

gcc l.uql.c y.uql.c -o uql -ll
/usr/lib/gcc/i686-pc-cygwin/3.4.1/../../../../i686-pc-cygwin/bin/ld: 
cannot find -ll
collect2: ld returned 1 exit status
make: *** [uql] Error 1

Does anybody know which package is required to build my application?
Any help would be appriciated.
