Let the plain truth be known: there is _no_ cygwin implementation of
OpenGL. The OpenGL package for Cygwin contains only headers that allow gcc
to correctly link with the opengl32.dll that comes with Windows or the one
that has been installed with your video card drivers. It is the exact same
implementation of OpenGL that is used by VC++.
So if there is a run time error with your program with gcc but not with
VC++ on the same computer, it can only be a fault with how OpenGL is
called, not with how OpenGL is implemented. One likely cause is
uninitialized variables that luckily get proper values with VC++, but not
with gcc.
