Apart from the base install, I have installed the opengl library and gcc and
the packages it requires (cygwin, ash, binutils, w32api, mingw-runtime,
linintl2, gcc-mingw). I already gave the build command:
gcc -glut32 -lglu32 -lopengl32 -o test test.c

Any other info needed? This is cygwin 1.3.18, packages were downloaded a
few weeks ago.
