# 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 |
