+ * Makefile.in (CFLAGS-opts.o): Pass in DOCUMENTATION_ROOT_URL via
+ -D.
+ * configure.ac (--with-documentation-root-url): New option.
+ * configure: Regenerate.
+ * diagnostic-format-json.cc (json_end_diagnostic): If there is an
+ option URL, add it as a new string field of the diagnostic option.
+ * diagnostic.c (diagnostic_initialize): Initialize get_option_url.
