6430# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6431# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6432# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6433#
6434# Of course, Automake must honor this variable whenever it calls a
6435# tool from the auxiliary directory.  The problem is that $srcdir (and
6436# therefore $ac_aux_dir as well) can be either absolute or relative,
6437# depending on how configure is run.  This is pretty annoying, since
6438# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6439# source directory, any form will work fine, but in subdirectories a
6440# relative path needs to be adjusted first.
6441#
6442# $ac_aux_dir/missing
6443#    fails when called from a subdirectory if $ac_aux_dir is relative
6444# $top_srcdir/$ac_aux_dir/missing
6445#    fails if $ac_aux_dir is absolute,
6446#    fails when called from a subdirectory in a VPATH build with
6447#          a relative $ac_aux_dir
6448#
6449# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6450# are both prefixed by $srcdir.  In an in-source build this is usually
6451# harmless because $srcdir is `.', but things will broke when you
6452# start a VPATH build or use an absolute $srcdir.
6453#
6454# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6455# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6456#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6457# and then we would define $MISSING as
6458#   MISSING="\${SHELL} $am_aux_dir/missing"
6459# This will work as long as MISSING is not called from configure, because
6460# unfortunately $(top_srcdir) has no meaning in configure.
6461# However there are other variables, like CC, which are often used in
6462# configure, and could therefore not use this "fixed" $ac_aux_dir.
6463#
6464# Another solution, used here, is to always expand $ac_aux_dir to an
6465# absolute PATH.  The drawback is that using absolute paths prevent a
6466# configured tree to be moved without reconfiguration.
