/* SDL stdinc inline functions:

   The theory here is that by default we forcibly inline what we can, and your
   app will use the inline version by default. However we expose a non-inline
   version too, so the symbol is always available in the library even if your app
   bypassed the inline version. The SDL_*_inline versions aren't guaranteed to
   exist, so never call them directly; use SDL_* instead, and trust the system
   to give you the right thing.

   The benefit here is that you can dlsym() these functions, which you
   couldn't if you had macros, you can link against a foreign build of SDL
   even if you configured differently, and you can drop the unconfigured SDL
   headers into a project without #defining HAVE_MALLOC (etc) and still link.
