 REVISION HISTORY

 Description: Changed file name to bitreorder_tab.c and .h. Also, updated the
              module description.

 Description: Define "const Word16 *reorderBits[NUM_MODES-1]" as
              "const Word16 *const reorderBits[NUM_MODES-1]".

 Description: Added #ifdef __cplusplus and removed "extern" from table
              definition. Removed corresponding header file from Include
              section.

 Description: Put "extern" back.

 RESOURCES USED
   When the code is written for a specific target processor the
     the resources used should be documented below.

 STACK USAGE: [stack count for this module] + [variable to represent
          stack usage for each subroutine called]

     where: [stack usage variable] = stack usage for [subroutine
         name] (see [filename].ext)

 DATA MEMORY USED: x words

 PROGRAM MEMORY USED: x words

 CLOCK CYCLES: [cycle count equation for this module] + [variable
           used to represent cycle count for each subroutine
           called]

     where: [cycle count variable] = cycle count for [subroutine
        name] (see [filename].ext)
