running make after ./configure results in error - Mailing list pgsql-cygwin

I followed the procedure listed in FAQ_MSWIN after installing PostGreSQL on
my win2k system using cygwin, After the ./compile procedure (which was
successful) there was some error in the make. The error is listed as
follows:

/usr/lib/gcc -lib/i686-pc-cygwin/2.95.3-5/../../../../i686-pc-cygwin/bin/ld:
cannot find -lcrypt
collect2: ld returned 1 exit status
make[2]: *** [postgres] Error 1
make[2]: Leaving directory '/usr/src/postgresql-7.1.3/src/backend'
make[1]: *** [install] Error 2
make[1]: Leaving directory '/usr/src/postgresql-7.1.3/src'
make: *** [install] Error 2

how do I solve this? thanks in advance!
