Well, now I should have a working win32 version.

• The code distinguishes between directory/file names and paths now
  (this breaks the Linux build).
• The order of Win32 compare-all-attributes is reversed now so that
  timestamps come last and DACLs imediately after type and size.
• Implemented a Win32 full directory cmparison (but note that SACLs
  are still not supported and hence not compared).
• A couple more fixes regarding segfaults etc.
