Subject: Compile error with glibc 2.3.2 + Linux 2.6.5 ARCH=x86_64

I am getting compiler errors when trying to compile glibc 2.3.2 using
the kernel headers from linux 2.6.5.  The headers from linux 2.6.3 work
fine.

I've traced the cause of the problem to a change made in
./include/asm-x86_64/unistd.h in the 2.6.4 release.

+#ifndef __ASSEMBLY__
+
+#include <linux/linkage.h>
+#include <linux/compiler.h>
+#include <linux/types.h>
+#include <asm/ptrace.h>
+
+asmlinkage long sys_ptrace(long request, long pid,
+                                unsigned long addr, long data);
+asmlinkage long sys_iopl(unsigned int level, struct pt_regs regs);
+asmlinkage long sys_ioperm(unsigned long from, unsigned long num, int
turn_on);
+struct sigaction;
+asmlinkage long sys_rt_sigaction(int sig,
+                                const struct sigaction __user *act,
+                                struct sigaction __user *oact,
+                                size_t sigsetsize);
+
+#endif  /* __ASSEMBLY__ */

Within glibc, ./sysdeps/unix/sysv/linux/x86_64/syscall.S ends up
including this file, which chokes the assembler with the struct
declarations in the above #include's.

/home/dlee/vcs/Products/Breeze/Dev/Prj/LinuxRH8/tscale2/tools/x86_64/x86
_64-linux/glibcinclude/linux/posix_types.h: Assembler messages:
/home/dlee/vcs/Products/Breeze/Dev/Prj/LinuxRH8/tscale2/tools/x86_64/x86
_64-linux/glibcinclude/linux/posix_types.h:36: Error: no such
instruction: `typedef struct{'

There are also errors about conflicting re-declarations further along in
the glibc build.

../posix/sys/types.h:62: error: conflicting types for `dev_t'
/home/dlee/vcs/Products/Breeze/Dev/Prj/LinuxRH8/tscale2/tools/x86_64/x86
_64-linux/glibcinclude/linux/types.h:23: error: previous declaration of
`dev_t'

Changing the '#ifndef __ASSEMBLY__' to '#if ((!defined __ASSEMBLY__) &&
(defined __KERNEL__))' clears up the problem.  My patch is below.
