You're not kidding about the identical part. in the documentation all 3 have 
the same numeric value (0x84F5).

I'd like to know if anyone has any qualms about the code below, we could have 
3 seperate ifs, but considering the above it'd be redundant code.

 /* All three of TEXTURE_RECTANGLE_(ARB|EXT|NV) are allocated the value 
0x84F5, so as long as one of them is there
    we can enable it using the same symbol for it, beats having 3 seperate 
ifs. */
 if (HAVE_GL_EXT(priv, ARB_TEXTURE_RECTANGLE) || HAVE_GL_EXT(priv, 
EXT_TEXTURE_RECTANGLE) || 
        HAVE_GL_EXT(priv, NV_TEXTURE_RECTANGLE))
  glEnable(TEXTURE_RECTANGLE_ARB);
