      Fix for Bug#38766 Falcon hangs during start-up if compiled for 64 bit SPARC
      
      Wrong CompareAndChange routine was used for in interlockedAdd. Replaced routine for
exchanging 
      pointers with routine for exchanging integer values. This problem resultet in errors
      on big-endian 64 bit machines.

  storage/falcon/Interlock.h

    Use the correct COMPARE_EXCHANGE routine for CompareAndSwap of integer types in
    interlockedAdd.
