+   History:
+   10.Dec.91	v1.0	First version <hf@pkinbg.uucp>
+   08.Feb.92	v1.1	Non-ANSI prototypes added <tdsimao@venus.cpqd.ansp.br>
+   11.Jan.96    v1.2    Fixed misleading prototype parameter names in
+                        alaw_expand() and ulaw_compress(); changed to
+			smart prototypes <simao@ctd.comsat.com>,
+			and <Volker.Springer@eedn.ericsson.se>
+   31.Jan.2000  v3.01   [version no.aligned with g711.c] Updated list of 
+                        compilers for smart prototypes
+   13jan2005            Byte for compressed data
