- unified snd_pcm_hw_params_* functions - added backward compatibility for older non-compatible functions - added --with-compat-rc3 to configure script to build library backwards compatible with 0.9.0rc3 - added symbol versioning like libc.so.6 - ALSA_0.9 - alsa base - ALSA_0.9.0rc4 - first set of new functions (snd_pcm_hw_params_*)

add support for hosts that have custom symbol prefixes From: Mike Frysinger <vapier@gentoo.org> some architectures, like Blackfin, have a prefix added to all symbols (in our case it's historical baggage) while normally packages shouldnt care, when code starts mixing assembler with C (like symbol versioning), you need to dip down into the inner details. find attached a patch which queries gcc for the prefix (all gcc toolchains have a builtin define of __USER_LABEL_PREFIX__) and then automatically has asm() constructs utilize this since most targets define __USER_LABEL_PREFIX__ to nothing, hopefully this shouldnt cause any problems :)

Portability fix for alsa-lib on mips From: Henryk Plötz <henryk@ploetzli.ch> I recently had problems building alsa-lib 1.0.10 on mips (for my Netgear WGT634U). Turned out the problem was in include/alsa-symbols.h were there was __asm__ code that wouldn't work with the mips assembler. Attached is a patch that makes this work again.
