patch to cron

[Andy Stevens]

Hello Cygwin patchers, this is my first submission, hope I do OK.

I have discovered a bug in Vixie's cron in the bash script
/usr/bin/cron-config. The bug only appears on Windows 10 which has
an NT version of "10.0". This breaks the version checking in the
bash script. (Bash only supports integer compare or ASCII compare,
but not float compare.)

Below is my proposed patch.  Thanks to
http://stackoverflow.com/questions/8654051 for this bash magic.
