I will go farther and say the objects simply will not work.
The object format is different, among other things.  Cygwin
is not a pure emulation -- it is a *Windows* library that tries
to make Windows look like Linux (Posix, actually), mostly.

Either you need to make the program build under cygwin, using
cygwin compilers, or port the program to Windows, or run inside
a virtual machine, such as Virtual Box.  Maybe a virtual machine
is your best bet here.
