* Fixed some bugs with incorrect macro usage (SDL_BYTE_ORDER vs
SDL_BYTEORDER, {MSC,GCC}_VER vs {MSC,GCC}_VERSION, OS_WIN/OS_UNIX in
projects where they're not defined).
* Removed some redundant declarations of g_Console.
* Removed some unnecessary semicolons.
* Removed some unused variables.
* Added throw specification to operator new.
This was SVN commit r4698.
