Allow users to define SDL_STDINC_NO_INLINES if they don't want the inline functions defined.
This is useful, for example, if the standard config defines HAVE_SETENV but you're building with C99 that doesn't include that feature.

/* SDL stdinc inline functions:
slouken@4761
   232
slouken@7005
   233
   The theory here is that by default we forcibly inline what we can, and your
slouken@7005
   234
   app will use the inline version by default. However we expose a non-inline
slouken@7005
   235
   version too, so the symbol is always available in the library even if your app
slouken@7005
   236
   bypassed the inline version. The SDL_*_inline versions aren't guaranteed to
slouken@7005
   237
   exist, so never call them directly; use SDL_* instead, and trust the system
slouken@7005
   238
   to give you the right thing.
slouken@4761
   239
icculus@7003
   240
   The benefit here is that you can dlsym() these functions, which you
icculus@7003
   241
   couldn't if you had macros, you can link against a foreign build of SDL
icculus@7003
   242
   even if you configured differently, and you can drop the unconfigured SDL
icculus@7003
   243
   headers into a project without #defining HAVE_MALLOC (etc) and still link.
slouken@7308
   244
slouken@7308
   245
   If you want to disable the inline functions and just use SDL's functions,
slouken@7308
   246
   you can define SDL_STDINC_NO_INLINES before including this file.
