# ---------------
# Check whether `mkdir -p' is known to be thread-safe, and fall back to
# install-sh -d 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 vulnerable to race conditions:
# 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 known race-free implementations.
#
# Automake used to define mkdir_p as `mkdir -p .', in order to
# allow $(mkdir_p) to be used without argument. As in
# $(mkdir_p) $(somedir)
# where $(somedir) is conditionally defined. However we don't do
# that for MKDIR_P.
# 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.
#
# On NextStep and OpenStep, the `mkdir' command does not
# recognize any option. It will interpret all options as
# directories to create.

\`configure' configures m4_ifset([AC_PACKAGE_STRING],

[this package]) to adapt to many kinds of systems.
Usage: $[0] [[OPTION]]... [[VAR=VALUE]]...
[To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:

[install architecture-independent files in PREFIX [$ac_default_prefix]])
AS_HELP_STRING([--exec-prefix=EPREFIX],
[install architecture-dependent files in EPREFIX [PREFIX]])[
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
