[lib/ChangeLog] Fix some Darwin-7.9.0 porting problems reported by Bruno Haible in <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00063.html>. * dirchownmod.c: Include lchown.h. * lchown.c: Don't include files that lchown.h now includes. Don't declare chown, since lchown.h now does that. * lchown.h: Include errno.h, sys/types.h, unistd.h. (lchown): Define to rpl_chown if lchown is declared but does not exist. Declare using a prototype if lchown is not declared. Add a copyright notice. * mkstemp.h: Include <unistd.h>. * openat.c: Include lchown.h. [m4/ChangeLog] * lchown.m4 (gl_FUNC_LCHOWN): Check whether lchown is declared.
