     38  REVISION HISTORY
     39 
     40  Description: Moved WMFBytesUsed and IF2BytesUsed tables from gsmamr_enc.h.
     41               Changed their type definition to 'const int'. Renamed tables to
     42               WmfEncBytesPerFrame and If2EncBytesPerFrame.
     43 
     44  Description: Added #ifdef __cplusplus and removed "extern" from table
     45               definition.
     46 
     47  Description: Put "extern" back.
