Fix incorrect check for iPhone macro in hwconsts.h TARGET_OS_IPHONE is always defined when building on Mac OS, so the define was wrong. This macro expands to either 0 or 1, so a simple #if should be enough.

#ifndef _SDLname_h_
#define _SDLname_h_

#if defined(__STDC__) || defined(__cplusplus)
#define NeedFunctionPrototypes 1
#endif

#define SDL_NAME(X) SDL_##X

#endif /* _SDLname_h_ */
