+       getdomainname: Use the system function when possible.
+       * lib/unistd.in.h: Include <netdb.h>, for getdomainname's declaration.
+       (getdomainname): Replace if needed. Provide the declaration if it is
+       missing. Don't use _GL_CXXALIAS_SYS_CAST.
+       * lib/getdomainname.c: Include <limits.h> and <sys/systeminfo.h>.
+       (getdomainname): When the system has getdomainname, call the system
+       function. When sysinfo (SI_SRPC_DOMAIN, ...) is possible, use that.
+       * m4/getdomainname.m4 (gl_FUNC_GETDOMAINNAME): Require
+       gl_HEADER_SYS_SOCKET and gl_HEADER_NETDB. Test whether the function is
+       found in libnsl. Look for the declaration also in <netdb.h>. Replace
+       the function if its second argument is of type 'int' or if it is found
+       in libnsl.
+       (gl_PREREQ_GETDOMAINNAME): Define HAVE_GETDOMAINNAME. Check for
+       <sys/systeminfo.h> and sysinfo().
+       * modules/getdomainname (Depends-on): Add netdb, sys_socket.
+       * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize
+       HAVE_DECL_GETDOMAINNAME and REPLACE_GETDOMAINNAME instead of
+       HAVE_GETDOMAINNAME.
+       * modules/unistd (Makefile.am): Substitute HAVE_DECL_GETDOMAINNAME and
+       REPLACE_GETDOMAINNAME instead of HAVE_GETDOMAINNAME.
+       * doc/glibc-functions/getdomainname.texi: Document the problems with
+       the getdomainname declaration.

        sys_socket: Ensure ss_family field on AIX.
        * lib/sys_socket.in.h (ss_family): New macro definition.
