+       better AC_REQUIRE expanded-before-required-warning avoidance
+       * m4/chown.m4 (gl_FUNC_CHOWN, gl_FUNC_CHOWN_FOLLOWS_SYMLINK): Define
+       with AC_DEFUN_ONCE, rather than AC_DEFUN, to avoid AC_REQUIRE warnings.
+       Suggested by Eric Blake.  This change also reverts commit 1b712ba8,
+       which is no longer needed.
