* locale/error.c, locale/error.h: Files removed. * locale/Makefile (distribute): Remove error.h. (lib-modules): Remove error. * hurd/hurdlookup.c (__hurd_file_name_lookup_retry): For "tty" magic, return ENXIO if no ctty. * sysdeps/mach/hurd/mmap.c: For MAP_FIXED, deallocate a previous mapping if vm_map fails for that reason. * posix/glob.c: Implement new options GLOB_ALTDIRFUNC, GLOB_BRACE, GLOB_TILDE, GLOB_NOMAGIC. (glob): Use stat instead of lstat to determine directoriness. * posix/glob.h (GLOB_ALTDIRFUNC, GLOB_BRACE, GLOB_NOMAGIC, GLOB_TILDE): New flag bits. (__GLOB_FLAGS): Include them. (glob_t): New members gl_closedir, gl_readdir, gl_opendir, gl_lstat, gl_stat. * elf/elf.h (ET_NUM, SHT_NUM, STB_NUM, STT_NUM, PT_NUM): New macros. * sysdeps/unix/sysv/linux/sys/mman.h: Include <linux/mman.h> to define all the bit values. (MAP_*, MCL_*): Macros removed.
