<><> Unix support infrastructure ><><><><><><><><><><><><><><><><><><><><><><><>


opam and the OCaml ecosystem in general require various Unix tools in order to operate correctly. At present, this requires the installation of Cygwin to provide these tools.


How should opam obtain Unix tools?
> 1. Use tools found in PATH (Cygwin installation at C:\cygwin64)
2. Automatically create an internal Cygwin installation that will be managed by opam (recommended)
3. Use Cygwin installation found in C:\cygwin64
4. Use another existing Cygwin/MSYS2 installation
5. Abort initialisation
