The Windows select function is only implemented for sockets. To implement a POSIX select function which allows to select on any descriptor one needs to implement it specificially for each known, resp. useful file type. Naturally this won't work with a generic Windows handle since Cygein doesn't know what it represents. So Cygwin is unable to provide a matching select function.
