+                               <LI>libFLAC, libOggFLAC: Can now be compiled to use only integer instructions, including encoding.  The decoder is almost completely integer anyway but there were a couple places that needed a fixed-point replacement.  There is no fixed-point version of LPC analysis yet, so if libFLAC is compiled integer-only, the encoder will behave as if the max LPC order is 0 (i.e. used fixed predictors only).  LPC decoding is supported in all cases as it always was integer-only.</LI>
