+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Modified to return the LPC coefficients in-place, so the
+ interface to tns_decode_coef is changed.
+
+ Description: Modified to return the q-format of the LPC coefficients.
+
+ Description: Modified so that only the function is declared here.  extern
+ references to constant tables removed.  Also, new copyright header included.
+
+ Description: Modified to include extra parameter, so tns_decode_coef can use
+ scratch memory techniques.
+
+ Description:
+ (1) Modified to include the lines...
+
+    #ifdef __cplusplus
+    extern "C" {
+    #endif
+
+    #ifdef __cplusplus
+    }
+    #endif
+
+ (2) Updated the copyright header.
+
+ Who:                       Date:
+ Description:
+------------------------------------------------------------------------------
+ INCLUDE DESCRIPTION
+
+ This function includes the function declaration for tns_decode_coef()
