I use the cygwin version quite a bit. Some versions of Windows use
PATH, while others use Path (this is a Windows thing and not a cygwin
thing). I have seen situation where I need to set both variables
before launched programs work properly (not sure if Windows or cygwin
was at fault here), so I am now in the habit of exporting Path :=
$(PATH) when using make (actually we're not using the make that comes
with cygwin, but we are using make 3.79 or 3.80 compiled using gcc
that comes with cygwin).

I know that cygwin messes with the PATH, since it converts the Windows
semi-colon separated list with backslashes into a colon separated list
with forward slashes.
