 * Revision 1.2  1996/08/20  20:31:21  jaf
 * Removed all static local variables that were SAVE'd in the Fortran

 * argument.
 *
 * Removed init function, since all initialization is now done in
 * init_lpc10_encoder_state().
 *
 * Changed name of function from lpcenc_ to lpc10_encode, simply to make
 * all lpc10 functions have more consistent naming with each other.
