+       Add support for universal builds to <inttypes.h>.
+       * lib/inttypes.in.h (_PRI64_PREFIX, _PRIu64_PREFIX, _SCN64_PREFIX,
+       _SCNu64_PREFIX): In Apple
+       universal builds, define directly, using _LP64.
+       * m4/inttypes.m4 (gl_INTTYPES_H): In Apple universal builds, set
+       INT64_MAX_EQ_LONG_MAX and UINT64_MAX_EQ_ULONG_MAX to -1.
+       * modules/inttypes (Depends-on): Add multiarch.
+       (Makefile.am): Substitute APPLE_UNIVERSAL_BUILD.
