41# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
42# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
43# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
44#
45# Of course, Automake must honor this variable whenever it calls a
46# tool from the auxiliary directory. The problem is that $srcdir (and
47# therefore $ac_aux_dir as well) can be either absolute or relative,
48# depending on how configure is run. This is pretty annoying, since
49# it makes $ac_aux_dir quite unusable in subdirectories: in the top
50# source directory, any form will work fine, but in subdirectories a
51# relative path needs to be adjusted first.
52#
53# $ac_aux_dir/missing
54# fails when called from a subdirectory if $ac_aux_dir is relative
55# $top_srcdir/$ac_aux_dir/missing
56# fails if $ac_aux_dir is absolute,
57# fails when called from a subdirectory in a VPATH build with
58# a relative $ac_aux_dir
59#
60# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
61# are both prefixed by $srcdir. In an in-source build this is usually
62# harmless because $srcdir is `.', but things will broke when you
63# start a VPATH build or use an absolute $srcdir.
64#
65# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
66# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
67# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
68# and then we would define $MISSING as
69# MISSING="\${SHELL} $am_aux_dir/missing"
70# This will work as long as MISSING is not called from configure, because
71# unfortunately $(top_srcdir) has no meaning in configure.
72# However there are other variables, like CC, which are often used in
73# configure, and could therefore not use this "fixed" $ac_aux_dir.
74#
75# Another solution, used here, is to always expand $ac_aux_dir to an
76# absolute PATH. The drawback is that using absolute paths prevent a
77# configured tree to be moved without reconfiguration.

620# This was a mistake. There are at least two reasons why we must not

622# - it causes special bits like SGID to be ignored,

631# concurrently, both version can detect that a/ is missing, but only
