Hello,

The compilation fails on MIPS with the new 2.6.9.1 kernel headers :

I think this issue has been discussed (and fixed) in the Linux MIPS CVS, see :
 http://www.linux-mips.org/archives/linux-mips/2004-10/msg00286.html
 http://www.linux-mips.org/archives/linux-cvs/2004-10/msg00120.html

As I understand it, #ifdef __KERNEL__ conditionnal is missing, leading to SOCK_* being visible to the userspace, and conflicting with libc definitions.
