+# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
+# created by `make install' are always world readable, even if the
+# installer happens to have an overly restrictive umask (e.g. 077).
+# This was a mistake. There are at least two reasons why we must not
+# use `-m 0755':
+# - it causes special bits like SGID to be ignored,
+# - it may be too restrictive (some setups expect 775 directories).
+#
+# Do not use -m 0755 and let people choose whatever they expect by
+# setting umask.
+#
+# We cannot accept any implementation of `mkdir' that recognizes `-p'.
+# Some implementations (such as Solaris 8's) are not thread-safe: if a
+# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
+# concurrently, both version can detect that a/ is missing, but only
+# one can create it and the other will error out. Consequently we
+# restrict ourselves to GNU make (using the --version option ensures
+# this.)
