  the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here.
  
  Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here.  Not 5 or 10 depending on the architecture.
  
  More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

  /* 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.
