-# 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.
