+# Running aclocal here first (as happened for a while) caused the macros that
+# libtoolize puts in the m4 directory to be newer than the aclocal.m4 file that
+# aclocal creates. This meant that the next "make" cause aclocal to be run
+# again. Moving aclocal to after libtoolize does not seem to cause any
+# problems, and it fixes this issue.
