Why do you think the mingw headers would work with Cygwin's compiler?

 From an API point of view, Cygwin is a POSIX system. If your software includes 
comutil.h/compip.h/comdep.h, that's a Windows application. You need a compiler 
which understands the Windows API and creates native Windows applications. 
Cygwin's GCC isn't such a compiler.

You need either a Mingw compiler, or Cygwin's cross compiler 
(mingw64-i686-gcc-g++-9.2.0-2 )
