  *) Adopt apr user/group name features for mod_rewrite.  Eliminates some
     'extra' stat's for user/group since they should never occur, and now
     resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
     volumes.

  No-one commented on loosing the 'stat' calls, can anyone invent a scenario
  where they could be required?  Also, I don't like the casts either, so if
  you have a better solution, don't whine, just fix it :)
