/* IMPORTANT:
   This is the master switch to disabling the dynamic API. We made it so you
   have to hand-edit an internal source file in SDL to turn it off; you
   can do it if you want it badly enough, but hopefully you won't want to.
   You should understand the ramifications of turning this off: it makes it
   hard to update your SDL in the field, and impossible if you've statically
   linked SDL into your app. Understand that platforms change, and if we can't
   drop in an updated SDL, your application can definitely break some time
   in the future, even if it's fine today.
   To be sure, as new system-level video and audio APIs are introduced, an
   updated SDL can transparently take advantage of them, but your program will
   not without this feature. Think hard before turning it off.
