 * 5/10/91  W. Joseph Carter    Reorganized & renamed all ".h" files  *
 *                              into "common.h" and "encoder.h".      *
 *                              Ported to Macintosh and Unix.         *
 *                              Added function prototypes for more    *
 *                              rigorous type checking.               *
 * 27jun91  dpwe (Aware)        moved "alloc_*" types, pros to common *
 *                              Use ifdef PROTO_ARGS for prototypes   *
 *                              prototypes reflect frame_params struct*
 * 7/10/91  Earle Jennings      Conversion of all floats to FLOAT     *
 * 10/3/91  Don H. Lee          implemented CRC-16 error protection   *
 *                              Additions and revisions are marked    *
 *                              with "dhl" for clarity                *

 *                              important fixes involved changing     *
 *                              16-bit ints to long or unsigned in    *
 *                              bit alloc routines for quant of 65535 *
 *                              and passing proper function args.     *
 *                              Removed "Other Joint Stereo" option   *
 *                              and made bitrate be total channel     *
 *                              bitrate, irrespective of the mode.    *
 *                              Fixed many small bugs & reorganized.  *
 *                              Modified some function prototypes.    *
 * 7/27/92  Masahiro Iwadare    FFT modifications for Layer 3         *
 * 8/3/92   Mike Li             removed declaration _stklen for DOS.  *
 * 9/22/92  jddevine@aware.com  Fix protos for _scale_factor_calc()   *
 * 11/04/94 Jon Rowlands        Fix protos for usage()                *
 * 07/11/95 Soeren H. Nielsen   Changed defs. and protos for LSF      *
