[CELT-dev] drawback when using very small frame sizes ?

The smaller the frame size, the higher the bit-rate required to get the
same quality. For tiny frame sizes, this is even more noticeable. As for
the compile flags, I think 0.9.1 still required the MIXED_PRECISION to
be defined for fixed-point. This is no longer the case for 0.10 and later.
