(__ctype_get_mb_cur_max): Make function weak. * new-malloc/malloc.c: Correct copyright. * new-malloc/thread-m.h: Correct key handling. * shadow/lckpwdf.c: Update copyright. (PWD_LOCKFILE): Change to /etc/.pwd.lock. * stdlib/strtod.c: Add another assertion. * stdlib/tst-strtod.c: Add another test case. * sysdeps/generic/paths.h: Add _PATH_PRESERVE. Needed by nvi. * sysdeps/unix/sysv/linux/paths.h: Likewise. * sysdeps/gnu/utmpbits.h: Rename ut_addr field to ut_addr_v6. ut_addr names a single element in ut_addr_v6. * sysdeps/mach/hurd/xmknod.c: Remove alias from __mknod to mknod.
