+	* scripts/versionlist.awk: New file.
+	* Makerules [$(build-shared) = yes]
+	(postclean-generated): Add Versions.def, not Versions.def.v and
+	Versions.def.v.i.
+	($(common-objpfx)Versions.def.v.i): Target removed.
+	($(common-objpfx)Versions.def): New target.
+	($(common-objpfx)Versions.all): Depend on that rather that
+	$(common-objpfx)Versions.def.v.
+	* Versions.def: File removed.
+
 	* Makeconfig (+gccwarn): Add -Wundef.
 	* include/errno.h [IS_IN_rtld] [!RTLD_PRIVATE_ERRNO]: #error to catch
 	a dl-sysdep.h breaking its contract.
