I've actually taken the scripts a bit further. Building GLIBC and GCC
from the raw kernel headers and only using the sanitized stuff for
everything else. On a few of the lists I have seen this done with
success and found out that this is the recommended build method for
GLIBC, still checking on the status GCC and this situation. I have
created http://ftp.jg555.com/headers/headers2 for the sanitized part of
my build, but use the raw non-sanitized headers installed in
/tools/linux-headers for GCC and GLIBC. copying them straight from the
kernel sources. I based my builds off of the current CLFS with minor
modifications which I will be posting in the wiki sometime this week.
Ran into difficulties tonight. Need to protect against kernel types
that conflict with glibc in linux/types.h.
From self sanitized headers (Jim's and Jurg's):
....
#include <linux/posix_types.h>
#include <asm/types.h>
#ifndef __KERNEL_STRICT_NAMES
typedef __u32 __kernel_dev_t;
typedef __kernel_fd_set fd_set;

typedef __kernel_off_t off_t;
typedef __kernel_pid_t pid_t;
typedef __kernel_daddr_t daddr_t;

I have exactly three instances of 'WANT_KERNEL_TYPES' in my /usr/include
tree. :-) I'm honestly not sure why they wern't ripped out completely
unless that is something that was PLD specific that was slipped in there
as it really doesn't hurt. Might want to check Redhat, Gentoo, Debian,
... sets to see what they do. The quick solution for xorg-server was to
remove both instances of linux/types.h in lnx_agp.c. I chose to add the
same protected ifdef to linux/types.h and drag in sys/types.h.
