GLUT support is already included in cygwin's openGL package.

Scrap that. Use cygwin's openGL package instead.

Wrong glut.h; glut functions are not properly declared; that leads to 
linking problems.

After you install cygwin's openGL package, please read 
/usr/doc/opengl-1.1.0/README.txt for usefull clues.
