Changes:
Alexander Leidinger: add non linear psymodel (compile time option, disabled by default), workaround a bug in gcc 3.0.3 (compiler options, based upon suggestions from various people, see archives and changelog for more)
Steve Lhomme: ACM wrapper (MS-Windows codec)
Steve Lhomme: less memory copying on stereo (interleaved) input
Takehiro Tominaga: Inter-channel masking, enables with --interch x option
For buggy versions of gcc compiler (2.96*), back off on some of the advanced compiler options
