# AM_PROG_MKDIR_P
# ---------------
-# Check whether `mkdir -p' is supported, fallback to mkinstalldirs otherwise.
-#
-# 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 mkdir (using the --version option ensures
-# this.)
+# Check for 'mkdir -p'.

- # allow $(mkdir_p) to be used without argument. As in
- # $(mkdir_p) $(somedir)
- # where $(somedir) is conditionally defined. However we don't do
- # that anymore.
- # 1. before we restricted the check to GNU mkdir, `mkdir -p .' was
- # reported to fail in read-only directories. The system where this
- # happened has been forgotten.
- # 2. in practice we call $(mkdir_p) on directories such as
- # $(mkdir_p) "$(DESTDIR)$(somedir)"
- # and we don't want to create $(DESTDIR) if $(somedir) is empty.
- # To support the latter case, we have to write
- # test -z "$(somedir)" || $(mkdir_p) "$(DESTDIR)$(somedir)"
- # so $(mkdir_p) always has an argument.
- # We will have better chances of detecting a missing test if
- # $(mkdir_p) complains about missing arguments.
- # 3. $(mkdir_p) is named after `mkdir -p' and we don't expect this
- # to accept no argument.
- # 4. having something like `mkdir .' in the output is unsightly.
