Oh, ok. Good.  :)

The video driver is going to have to handle it eventually, so it's best 
to just check for NULL when it gets to the driver-specific 
implementation of SDL_GL_LoadLibrary()...

We'll probably come to a point someday where some platform moved a 
crucial library and we need to check two places or a system version 
number, so having this in driver-specific code instead of an #ifdef is 
useful for future protection.
