+
+ * Makerules ($(common-objpfx)Versions.v.i): Depend on abi-versions.h.
+
+ * Makeconfig (%.v.i, %.v): New implicit rules.
+ (preprocess-versions): Variable removed.
+ ($(common-objpfx)shlib-versions.v.i): New target giving just the
+ shlib-versions input files as dependencies.
+ ($(common-objpfx)soversions.i): Depend on that instead of the input
+ files. Use it as input instead of using a pipeline.
+ (postclean-generated): Append soversions.i, shlib-versions.v, and
+ shlib-versions.v.i here.
+ * Makerules ($(common-objpfx)Versions.def.v.i): New target giving just
+ the Versions.def input files as dependencies.
+ ($(common-objpfx)Versions.v.i): Likewise for Versions files.
+ ($(common-objpfx)Versions.all): Depend on that instead of the input
+ files. Use it as input instead of using a pipeline.
+ ($(common-objpfx)sysd-versions): Likewise with Versions.v.i.
+ (postclean-generated): Append those .v and .v.i files here.

* locale/broken_cur_max.c (__ctype_get_mb_cur_max): Use nl_langinfo.
