  Revert previous change and use Madhu's solution
  
  Madhu provided this patch to fix the issue he was encountering with
  probe-file that was calling unix-stat which was failing for him.  (I
  don't have that problem for whatever reason.)
  
  This changes `time-t` to be an `int64-t` type and adds
  `-D_TIME_BITS=64` to the compilation flags on Linux.
  
  I initially had issues with this patch, but it was fixed by removing
  all the build directories.
