Thanks fredborg!

There does not seem to be a global for glActiveTextureARB , so I think the right way is: (added gl_1.4 to 2.0 )

		glewInit() ' required for glActiveTextureARB

		If (GL_VERSION_1_3 | GL_VERSION_1_3 | GL_VERSION_1_4 | GL_VERSION_1_5 | GL_VERSION_2_0)
			Notify "OpenGL 1.3 or better present"
			multitexturePresent = True
		ElseIf (GL_ARB_multitexture)
			multitexturePresent = True
			Notify "GL_ARB_multitexture OK"
		Else
			Notify "GL_ARB_multitexture MISSING!"		
		EndIf
