 * 2/25/91  Doulas Wong,        start of version 1.0 records          *
 *          Davis Pan                                                 *
 * 5/10/91  W. Joseph Carter    Reorganized & renamed all ".h" files  *
 *                              into "common.h" and "encoder.h".      *
 *                              Ported to Macintosh and Unix.         *
 *                              Added additional type definitions for *
 *                              AIFF, double/SANE and "bitstream.c".  *
 *                              Added function prototypes for more    *
 *                              rigorous type checking.               *
 * 27jun91  dpwe (Aware)        Added "alloc_*" defs & prototypes     *
 *                              Defined new struct 'frame_params'.    *
 *                              Changed info.stereo to info.mode_ext  *
 *                              #define constants for mode types      *
 *                              Prototype arguments if PROTO_ARGS     *
 * 5/28/91  Earle Jennings      added MS_DOS definition               *
 *                              MsDos function prototype declarations *
 * 7/10/91  Earle Jennings      added FLOAT definition as double      *
 *10/ 3/91  Don H. Lee          implemented CRC-16 error protection   *
 * 2/11/92  W. Joseph Carter    Ported new code to Macintosh.  Most   *
 *                              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.    *
 *                              Changed BUFFER_SIZE back to 4096.     *
 * 7/27/92  Michael Li          (re-)Ported to MS-DOS                 *

 *                              AIFF string constants redefined       *
 * 8/27/93 Seymour Shlien,      Fixes in Unix and MSDOS ports,        *
 *         Daniel Lauzon, and                                         *

 *                              modes.                                *
