Fix incompatibility with <GL/glext.h>

New extensions in glext.h follow the pattern: #ifndef GL_ARB_texture_rectangle #define GL_ARB_texture_rectangle 1 #define GL_TEXTURE_RECTANGLE_ARB 0x84F5 #define GL_TEXTURE_BINDING_RECTANGLE_ARB 0x84F6 #define GL_PROXY_TEXTURE_RECTANGLE_ARB 0x84F7 #define GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB 0x84F8 #endif /* GL_ARB_texture_rectangle */ Versions.h tries to declare: const char* const GL_ARB_texture_rectangle = "GL_ARB_texture_rectangle"; Which means, if you've included glext.h before Versions.h, that the compiler will see "const char* const 1 = ...", and rightly refuse to continue. The ham-fisted approach taken here is to rename the variables in Versions.h with a leading underscore. This does sort of undermine the comment about "better to have the compiler do spelling checks", but. Signed-off-by: 's avatarAdam Jackson <ajax@redhat.com>
