Hello,
The following patch is needed to build alsa-libs 0.9beta9 or
0.9beta10 against the current Linux 2.4.17-rc1 kernel on ppclinux.
The definitions for mb, rmb and wmb are directly from the
asm-ppc/system.h header in Linux 2.4.16.
This patch has already been accepted by the Debian alsa maintainer.
Can we please get this in the alsa-libs cvs? Thanks in advance.
Jack
