* sysdeps/gnu/Versions: New file. * sysdeps/unix/sysv/linux/Versions (libc: GLIBC_2.1): Remove _sys_errlist; sys_errlist; _sys_nerr; sys_nerr; from here. * sysdeps/gnu/Makefile ($(..)sysdeps/gnu/errlist-compat.c): New target. ($(objpfx)errlist.d): Depend on $(..)sysdeps/gnu/errlist-compat.c. * sysdeps/gnu/errlist.awk: Make output define _sys_errlist_internal and _sys_nerr_internal instead of anything else. Make it include "errlist-compat.c" if [!NOT_IN_libc && !ERRLIST_NO_COMPAT]. Make it emit some asm magic if [EMIT_ERR_MAX]. * sysdeps/gnu/errlist.c: Regenerated. * sysdeps/gnu/errlist-compat.awk: New file. * sysdeps/gnu/errlist-compat.c: New file (generated). * sysdeps/mach/hurd/errlist.c (ERRLIST_NO_COMPAT): New macro. (_sys_errlist_internal): Define this as a macro for _hurd_errlist. (_sys_nerr_internal): Define this is a macro for _hurd_nerr. (SYS_ERRLIST, SYS_NERR): Macros removed. (sys_nerr, _sys_nerr): Remove these weak aliases. * sysdeps/unix/sysv/linux/errlist.c: File removed. * sysdeps/unix/sysv/linux/errlist.h: File removed. * sysdeps/unix/sysv/linux/arm/errlist.c: File removed.
