My currently employer's firewall does not allow access to external
CVS servers. I checked out monit from CVS on my home server and copied
it to my workstation. There seem several changes from the CVS version
to the published 4.8.1 version I am testing on. I am including at the
bottom of this message the very few changes I made to get version
4.8.1 to work under cygwin. I have executed monit in a dos box by
modifying the %PATH% variable to include the $CYGWIN_HOME\bin directory.

The changes I made to work with cygwin are:
- in monitor.h add a section at the bottom detecting __CYGWIN__
  and defining ICMP_ECHO as 8 and ICMP_ECHOREPLY as 0
- modify net.c putting a #ifdef __CYGWIN__ around icmp_echo() so
  if in a cygwin environment a stub function returns FALSE and
  disallows ICMP testing, in other environments the code compiles
  the real icmp_echo() function
