New NVIDIA OpenGL Extensions Headers

The new OpenGL headers files contain new extensions stuff. You can download them from… just a second, I start GPU Caps Viewer and… okay I got it :thumbup: : from developer.nvidia.com/object/nvidia_opengl_specs.html.

But there are a couple of weird things:

1 – the glext.h version is 28 (#define GL_GLEXT_VERSION 28). The version I use to compile the oZone3D engine renderer is the 29. And I use this header since more than one year…

2 – the glext.h header does not compile with vc6 (yes I still use visual studio 6!) because of the GL_EXT_timer_query extension. Here is the origianl piece of code you can find in glext.h:

/*
* Original code - does not compile with vc6.
*/
#ifndef GL_EXT_timer_query
typedef signed long long GLint64EXT;
typedef unsigned long long GLuint64EXT;
#endif

and here is the code I updated for visual c 6:

/*
Modified code for oZone3D engine - compile with vc6
*/
#ifndef GL_EXT_timer_query
	#ifdef _WIN32
		typedef signed __int64 GLint64EXT;
		typedef unsigned __int64 GLuint64EXT;
	#else
		typedef signed long long GLint64EXT;
		typedef unsigned long long GLuint64EXT;
	#endif
#endif

I wonder if the original glext.h compiles with vc7 or vc8. If anyone has the answer, feel free to contact me…
