   233 
   234    The theory here is that by default we forcibly inline what we can, and your
   235    app will use the inline version by default. However we expose a non-inline
   236    version too, so the symbol is always available in the library even if your app
   237    bypassed the inline version. The SDL_*_inline versions aren't guaranteed to
   238    exist, so never call them directly; use SDL_* instead, and trust the system
   239    to give you the right thing.
   240 
   241    The benefit here is that you can dlsym() these functions, which you
   242    couldn't if you had macros, you can link against a foreign build of SDL
   243    even if you configured differently, and you can drop the unconfigured SDL
   244    headers into a project without #defining HAVE_MALLOC (etc) and still link.
