Place the awk script (courtesy of Wenju Jiang, Columbia University) and
the IETF rfc3951.txt file in the same directory, and then type 
the following command:

awk -f extract-cfile.awk rfc3951.txt

Correct an error in file constants.c:
After line 13    #include "iLBC_define.h"
add the following line:
   #include "constants.h"

The end of file syntFilter.c contains after line 68 text that is not 
source code.

Source code was formated with indent:
