test if an unsigned long fits in a limb.

  Is there any other supported platform that has chosen an ABI where
  "Long" is smaller than the native word size?

Several RISCs define an ABI where long and pointers are 32 bits, and
registers and long long are 64 bits.  MIPS n32, HPPA 2.0N, the PowerPC
ABI used by GNU/Linux and *BSD are examples.

It is not clear if 'word' there is 32 bits or 64 bits large...
