        This files holds the variable declarations for the encoder and
	decoder (GSM specification 06.10) and comfort noise functions in the 
	encoder (GSM spec. 06.12) and Discontinuous Transmission functions
	in the encoder (GSM spec. 06.11).  This file is used when the 
	assembler directive "-Dalias" is NOT specified.
