5957# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
5958# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
5959# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
5960#
5961# Of course, Automake must honor this variable whenever it calls a
5962# tool from the auxiliary directory.  The problem is that $srcdir (and
5963# therefore $ac_aux_dir as well) can be either absolute or relative,
5964# depending on how configure is run.  This is pretty annoying, since
5965# it makes $ac_aux_dir quite unusable in subdirectories: in the top
5966# source directory, any form will work fine, but in subdirectories a
5967# relative path needs to be adjusted first.
5968#
5969# $ac_aux_dir/missing
5970#    fails when called from a subdirectory if $ac_aux_dir is relative
5971# $top_srcdir/$ac_aux_dir/missing
5972#    fails if $ac_aux_dir is absolute,
5973#    fails when called from a subdirectory in a VPATH build with
5974#          a relative $ac_aux_dir
5975#
5976# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
5977# are both prefixed by $srcdir.  In an in-source build this is usually
5978# harmless because $srcdir is `.', but things will broke when you
5979# start a VPATH build or use an absolute $srcdir.
5980#
5981# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
5982# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
5983#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
5984# and then we would define $MISSING as
5985#   MISSING="\${SHELL} $am_aux_dir/missing"
5986# This will work as long as MISSING is not called from configure, because
5987# unfortunately $(top_srcdir) has no meaning in configure.
5988# However there are other variables, like CC, which are often used in
5989# configure, and could therefore not use this "fixed" $ac_aux_dir.
5990#
5991# Another solution, used here, is to always expand $ac_aux_dir to an
5992# absolute PATH.  The drawback is that using absolute paths prevent a
5993# configured tree to be moved without reconfiguration.

6547# created by `make install' are always world readable, even if the
6548# installer happens to have an overly restrictive umask (e.g. 077).
6549# This was a mistake.  There are at least two reasons why we must not
6550# use `-m 0755':
6551#   - it causes special bits like SGID to be ignored,
6552#   - it may be too restrictive (some setups expect 775 directories).

6555# setting umask.

6558# Some implementations (such as Solaris 8's) are not thread-safe: if a
6559# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
6560# concurrently, both version can detect that a/ is missing, but only
