OpenGL loader and ES/core compatibility questions

  1. Spec says GL4.x is compatible with ES3.y.
    Does it mean that I can include GL4.x headers to compile ES3.y code?

  2. Which GL loader can generate explicit function table?

(what to avoid)
     s = glGetString(xxx);
(want to have)
     funcs = loader_init();
     s = funcs->glGetString(xxx);

Or at least, I would like to have ES3/GL4 stuffs compiled and linked anywhere without ifdef.

still looking for solution
