   241 
   242    The theory here is that by default we forcibly inline what we can, and your
   243    app will use the inline version by default. However we expose a non-inline
   244    version too, so the symbol is always available in the library even if your app
   245    bypassed the inline version. The SDL_*_inline versions aren't guaranteed to
   246    exist, so never call them directly; use SDL_* instead, and trust the system
   247    to give you the right thing.
   248 
   249    The benefit here is that you can dlsym() these functions, which you
   250    couldn't if you had macros, you can link against a foreign build of SDL
   251    even if you configured differently, and you can drop the unconfigured SDL
   252    headers into a project without #defining HAVE_MALLOC (etc) and still link.
