  (gl_PREREQ_CHOWN): Delete.
  * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add witness.
  * modules/unistd (Makefile.am): Populate it.
  * lib/unistd.in.h (chown): Update declaration.
  * lib/lchown.c (chown): Update client.
  * modules/lchown (Depends-on): Add lstat.
  * doc/posix-functions/chown.texi (chown): Document the bug.
  * doc/posix-functions/getgroups.texi (getgroups): Document
  getgroups pitfall.
  * modules/chown-tests: New file.
  * tests/test-chown.h (test_chown): Likewise.
  * tests/test-chown.c (main): Likewise.
