This is not a vim problem, I think this happens a lot with cygwin.
Take Tony's sugestion and update your cygwin packages to the latest versions.
In particular look up "cygwin rebase". Doing a rebase fixes most of these problems (at least for a while).

If you install the windows version and check the option to install the bat files then you can type
> gvim.bat -d file1 file1

and have gvim diff the files or whatever you want to do.
You can create an alias to make this easier on you:
alias g='gvim.bat'
