It's not enough to do that at compile time, since some targets support
running both 32-bit and 64-bit programs (e.g., ppc64-linux). You can
check at runtime, if you have a struct gdbarch nearby:

  struct gdbarch_tdep *tdep = gdbarch_tdep (gdbarch);

  if (tdep->wordsize == 4)
    {
      ...
    }

 if (tdep->wordsize == 8)
    {
      ...
    }
