If you are running inside Cygwin, then I would expect isunix to return
true, becuase you have a mostly Unix-like system that you can use.

But, I would also expect windows to return true, because you are
running on a Windows system.  The code to set these is

      bool unix_system = true;
      bool windows_system = false;

#if defined (WIN32)
      windows_system = true;
#if !defined (__CYGWIN__)
      unix_system = false;
#endif
#endif

      m.assign ("unix", octave_value (unix_system));
      m.assign ("windows", octave_value (windows_system));

in toplevel.cc.  So is WIN32 not defined by gcc on Cygwin systems now?
What should we use to check this?
