* New PowerPC fixed-point assembly courtesy of David Blythe.
* Reorganized fixed-point assembly routines for easier maintenance and
better performance.
* Improved performance of subband synthesis through better indexing and
fewer local variables.
* Added alias reduction for the lower two subbands of mixed short blocks,
per a report of ambiguity with ISO/IEC 11172-3 and for uniformity with
most other implementations. Also improved alias reduction performance
using multiply/accumulate.
* Added --enable-strict-iso option to `configure' to override best
accepted practices such as the alias reduction for mixed short blocks.
* Improved performance of Layer III IMDCT by using longer
multiply/accumulate runs where possible.
