That function just returned true for years not doing anything. As far as I can see from the web it's about some rare cases in DOS compatibility mode with 32-bit apps. But not sure why it was called exactly in this place in the past. So no comments, no idea what it's about and not actually doing anything and probably not needed on any platform anyone still uses ... lets just kick it out. (it did break compiling IRRLICHT_FAST_MATH on x64 which is why I noticed it) git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6009 dfc29bdd-3216-0410-991c-e03cc46cb475
