Use /proc/cygdrive/c/... in case it ever changes, and specify absolute paths for
scripts and commands, as only minimal environments are setup, and
non-interactive shell startup scripts run.
Might need to specify other environment variables required in the crontab.
Ensure your perl script has Cygwin +x permissions and hashbang line.

Add cron users to /var/cron/cron.allow (and maybe also a cron group), or touch
/var/cron/cron.deny to allow all users: see crontab(1).
Check /etc/crontab and /etc/cron.d/* are owned and writable only by the crond
user if they exist; /var/run/cron.pid and /var/log/cron.log exist and are owned
and writable only by the crond user; /var/cron/tabs/* exist and are owned by
their users and writable only by their owners; /var/run/cron.pid contains the
cron pid, and see what's in /var/log/cron.log.
