Tested on a sh4-linux-gnu build. Also with this issues, is there are strong reason to *not* have include guards on kernel-features.h? With current approach, a architecture can't include Linux default kernel-features.h and redefine it to a different value, only undefine it (unless it explicit do not include default kernel-features.h, and I think that's is not the idea). * sysdeps/unix/sysv/linux/sh/kernel-features.h: Add include guards. --- ChangeLog | 5 +++++ sysdeps/unix/sysv/linux/sh/kernel-features.h | 5 +++++ 2 files changed, 10 insertions(+) diff --git a/sysdeps/unix/sysv/linux/sh/kernel-features.h b/sysdeps/unix/sysv/linux/sh/kernel-features.h index ea4fdbc..d03aafa 100644 --- a/sysdeps/unix/sysv/linux/sh/kernel-features.h +++ b/sysdeps/unix/sysv/linux/sh/kernel-features.h @@ -17,6 +17,9 @@ License along with the GNU C Library; if not, see . */ +#ifndef __KERNEL_FEATURES_SH__ +# define __KERNEL_FEATURES_SH__ + /* SH uses socketcall. */ #define __ASSUME_SOCKETCALL 1 @@ -50,3 +53,5 @@ the kernel interface for p{read,write}64 adds a dummy long argument before the offset. */ #define __ASSUME_PRW_DUMMY_ARG 1 + +#endif
