3886# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
3887# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
3888# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
3889#
3890# Of course, Automake must honor this variable whenever it calls a
3891# tool from the auxiliary directory. The problem is that $srcdir (and
3892# therefore $ac_aux_dir as well) can be either absolute or relative,
3893# depending on how configure is run. This is pretty annoying, since
3894# it makes $ac_aux_dir quite unusable in subdirectories: in the top
3895# source directory, any form will work fine, but in subdirectories a
3896# relative path needs to be adjusted first.
3897#
3898# $ac_aux_dir/missing
3899# fails when called from a subdirectory if $ac_aux_dir is relative
3900# $top_srcdir/$ac_aux_dir/missing
3901# fails if $ac_aux_dir is absolute,
3902# fails when called from a subdirectory in a VPATH build with
3903# a relative $ac_aux_dir
3904#
3905# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
3906# are both prefixed by $srcdir. In an in-source build this is usually
3907# harmless because $srcdir is `.', but things will broke when you
3908# start a VPATH build or use an absolute $srcdir.
3909#
3910# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
3911# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
3912# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
3913# and then we would define $MISSING as
3914# MISSING="\${SHELL} $am_aux_dir/missing"
3915# This will work as long as MISSING is not called from configure, because
3916# unfortunately $(top_srcdir) has no meaning in configure.
3917# However there are other variables, like CC, which are often used in
3918# configure, and could therefore not use this "fixed" $ac_aux_dir.
3919#
3920# Another solution, used here, is to always expand $ac_aux_dir to an
3921# absolute PATH. The drawback is that using absolute paths prevent a
3922# configured tree to be moved without reconfiguration.
