chown(name,geteuid(),-1) failed to update the change time if name was already owned by the current effective user. Work around it by using chmod, which does not have this bug. Unfortunately, lchown has the same bug, but OpenBSD 4.0 lacks lchmod and lutimes, so there is no way to affect ctime without unlinking and recreating the symlink, which is too dangerous. * lib/chown.c (rpl_chown): Work around the bug. * lib/lchown.c (rpl_lchown): Attempt to do likewise. * m4/chown.m4 (gl_FUNC_CHOWN): Test for ctime bug. * m4/lchown.m4 (gl_FUNC_LCHOWN): Check for lchmod. * modules/chown (Depends-on): Add stdbool. * modules/lchown (Depends-on): Likewise. * doc/posix-functions/chown.texi (chown): Document the bug. * doc/posix-functions/lchown.texi (lchown): Likewise. * tests/test-lchown.h (test_chown): Relax test.
