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

 From: "David Lee" david.lee@xxxxxxxxxxxx

 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.
