Fix t/64bit.t test failure in Windows.

t/64bit.t .. 1/6
   Failed test 'expected (faked) value of total_malloced'
   at t/64bit.t line 30.
          got: '32'
     expected: '4294967328'
   Failed test 'hit size limit'
   at t/64bit.t line 41.
In Windows, long is just 32-bit even for 64-bit platforms.
