What you're observing is how the application itself handles paths
incoming from the command line.  An innocent POSIX application
might be inclined to check for a leading slash and if it's missing,
treat the path as relative.

The best way forward is to use POSIX path throughout and to convert
incoming Windows paths from native tools using cygpath(1) as described
in https://cygwin.com/cygwin-ug-net/using-utils.html#cygpath
