FWIW, I'd actually expect it to be the other way around: to hear that Make 3.81 considered a backslash to be a directory separator, whereas Make 4.3 did not. That's because some years ago the Cygwin developers decided they want no longer support native MS-Windows file names, only Posix- style file names. But other than that, I agree with Paul: this should probably be taken up with the Cygwin developers through their mailing list.
