Package: linux-libc-dev
Version: 2.6.28-1
Severity: serious
Tags: patch
linux-libc-dev has changed the way <asm/byteorder.h> declares endianness
related #define, and they conflict with <endian.h> at least on mips and
mipsel. This is something fixed upstream, please find below the upstream
patch and a less invasive patch.
