For the same reason as the original cron does it, I guess.
On Win9X it is typically a large user environment, including functions
in the case of bash. On NT it is only the small service environment.
Also the functions screw up the mail headers (because "}>" isn't a valid 
mail header), as in

The message will be there if needed. Currently it can be there even
when mail succeeds (wait() can return -1).

Just had a cup of coffee and I noticed in my cron.sh:
- it's silly to check if /usr/sbin exists because that's where
cron.exe was installed.
- it's safer to link /usr/sbin/ssmtp (without .exe).

3.0.1-9:
--------

The mail command is /usr/sbin/sendmail, which is a symlink preset to 
/usr/sbin/ssmtp . Prevent unnecessary syslog messages.
On Win9x, do not propagate the environment (see 3.0.1-3) and have crontab.exe
touch the file /etc/crontab instead of the directory /var/cron/tabs.
