	Another site (ftp) to get the SGI 1.2 OpenGL headers is

		ftp://ftp.teleport.com/pub/users/pgarceau/

	This archive includes the .def and  .a  (lib) files already 
converted from the MS .lib files for use with crtdll.dll based 
version of Mingw32 (GCC-2.8.x).

	Included with the archive, you will find a fairly extensive 
tutorial and cross-reference for the OpenGL API v1.2.  This is 
included as part of sgi-opengl2.exe.

	The header files are the original SGI OpenGL  v1.2 version of 
gl.h and glu.h.  The language is C.  glut.h is not included.

	If you need the C++ language stuff, then it looks like you'll 
be better off getting the V IDE.

	If you aren't using C++, then all that is necessary is that you 
link the respective mingw32 lib files (.a) at compile time.

	There really isn't a lot available for GCC for Win32.  The 
closest you might be able to find is written with the Win32 
(Win9x) platform in mind since it makes extensive use of the MS 
OpenGL Aux API.

	If you can manage getting around the MS OpenGL Aux (MS specific 
"glut") stuff, is, "OpenGL Superbible -- The Complete Guide to 
OpenGL Programming for Windows NT and Windows 95" from the Waite 
Group Press.

	Bear in mind that the title above is based on v1.1 of OpenGL (C 
language), and does not include any coverage of those things 
added to the OpenGL API as of version 1.2.

	Hope this helps.

	Peace,
