The "IS_32BIT" define in the FAQ should be replaced with some define or macro
that you can use on your platforms to detect that a 32bit build is requested.
Or perhaps it is easier to detect a 64bit build but the point is the same.

Which specific define to check depends on your system and your preference
really.

One possibility is to use a known define that sets a limit. Like this:

  #include <stdint.h>
  #if UINTPTR_MAX == 0xffffffff
  /* 32-bit */
  #else
  /* non 32bit */
  #endif
