Windows 10

Cygwin allows you to compile linux programs on windows systems by providing the full set of Linux functions your application might expect to see. It even converts filenames into a format Linux applications are used to and therefore uses "/cygdrive/c" instead of "C:\" in pathnames.
Any "real" windows application that uses windows function calls for accessing files won't be able to find out where that file is supposed to be and therefore is bound to fail in that case.

Kind regards,
