Subject: Re: SDL 1.2.6
- minor changes about shared library building under QNX6 into README.QNX
- added forgotten libSDLmain.a into distribution, SDL.qpg.in
- added header guards to the all headers.
- fixed fullscreen double buffered mode.
- fixed Photon crashes after/during using fullscreen OpenGL modes.
- added GL_MakeCurrent function.
- added SDL_VIDEOEXPOSE event, when OpenGL window have been resized
- added more HAVE_OPENGL checks to avoid dead code compilation without using OpenGL
- finished code reorganization (began into previous patches).
