# ---------------
# 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 make (using the --version option ensures
# this.)

# for two reasons:
# 1. if the package is installed by a user who cannot write `.'
# make install will fail,
# 2. the above comment should most certainly read
# $(mkdir_p) $(DESTDIR)$(somedir)
# so it does not work when $(somedir) is undefined and
# $(DESTDIR) is not.
# To support the latter case, we have to write
# test -z "$(somedir)" || $(mkdir_p) $(DESTDIR)$(somedir),
# so the `.' trick is pointless.
