  I was only alerted to the problem because the mpz/reuse.exe test took
  around 4 to 5 times longer to run on the 32-bit build than on the
  64-bit build. (The timing was around 70 seconds for 32-bit, and
  15seconds for 64-bit.)
  With RC2, the timing for 32-bit mpz/reuse.exe has dropped from 70
  seconds to 30 seconds - which is still much slower than for the 64-bit
  build.  I assume that comparative slowness is *not* indicative of a
  problem with the gmp library. (I mention it only in case that
  assumption ought to be challenged.)
Usually, a 64-bit libgmp will be 3 to 4 times faster than a 32-bit
libgmp.  This is assuning that 64-bit instructions are no slower than
32-bit instructions.
