Log Message:
Update to mad-0.12.4b.  Changes from 0.12.3b are:

  * 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.
