34 REVISION HISTORY
35
36 Description: Changed file name to bitreorder_tab.c and .h. Also, updated the
37              module description.
38
39 Description: Define "const Word16 *reorderBits[NUM_MODES-1]" as
40              "const Word16 *const reorderBits[NUM_MODES-1]".
41
42 Description: Added #ifdef __cplusplus and removed "extern" from table
43              definition. Removed corresponding header file from Include
44              section.
45
46 Description: Put "extern" back.
