+
+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Modified to eliminate triple-nested structure, which wasted
+ 2 KB of memory.
+
+ Description:
+ (1) Modified to include the lines...
+
+    #ifdef __cplusplus
+    extern "C" {
+    #endif
+
+    #ifdef __cplusplus
+    }
+    #endif
+
+ (2) Updated the copyright header.
+
+ Description:
+ (1) Changed hard coded size of arrays from "8" to "TNS_MAX_WIN"
+ (2) Moved elements from s_TNSinfo.h up to the level of TNS_frame_info
+ (3) Added Bool "tns_data_present" for future use.
+ (4) Moved lpc_coef up from s_TNSfilt.h (allowed for use of smaller array.)
+
+ Description:
+ (1) Removed the array "coef_res", which is now a local variable on the
+ stack inside get_tns.c
