+  - Aclocal no longer consider directories for extra m4 files more than
+    once, even if they are specified multiple times.  This prevents
+    problems in older packages that specify both

+    If the 'm4' directory did not exist when aclocal was called the first
+    time by autoreconf, an error would have ensued with Automake 1.13 and
+    1.13.1.  See automake bug#13514.
