+# This used to have a clause that exited with an error if MAKEINFO = no.
+# But it is inappropriate to do so without checking if makeinfo is
+# actually needed - it is not if the info files are up-to-date. (Bug#3982)
+# Only the doc/*/Makefiles can decide that, so we let those rules run
+# and give a standard error if makeinfo is needed but missing.
+# While it would be nice to give a more detailed error message, that
+# would require changing every rule in doc/ that builds an info file,
+# and it's not worth it. This case is only relevant if you download a
+# release, then change the .texi files.
