+       * bootstrap.conf (gnulib_modules): Add all the printf modules
+       suggested by -DGNULIB_POSIXCHECK.  Add realloc-posix as
+       suggested by -DGNULIB_POSIXCHECK for gnulib's own vasnprintf.c.
+       (excluded_files): Remove m4/printf-posix.m4.
+       * tests/atlocal.in (LIBS): As for LDADD in src/local.mk, add
+       lib/libbison.a so gnulib libraries can be linked.
