I recently tried to lay my hands on OpenGL. Trying to grasp the API, I learned (or was given the advice) that I shouldn't use glBegin and glEnd anymore, since those are deprecated, but should start with OpenGL 3.1, instead. As I didn't know that the version used makes such a difference, I didn't pay much attention as to which version I actually have installed on my computer. And, as far as I can see, there is no glVersion or similar call that I could use to determine that version.

I am using MinGW and I found the following lines in c:\MinGW\include\GL\gl.h:

/*
 * Mesa 3-D graphics library
 * Version:  4.0

 */

#define GL_VERSION_1_1   1

#if !defined(__WIN32__)
#define GL_VERSION_1_2   1
#define GL_VERSION_1_3   1
#define GL_ARB_imaging   1
#endif

 [more lines]

#define GL_VERSION                              0x1F02

which, to me, indicates, that the installed version is as low as 1.3. Is this the case or how could I verify my suspicion? Also, where would I find a later version if I have 1.3 only?
