96# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
97# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
98# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
99#
100# Of course, Automake must honor this variable whenever it calls a
101# tool from the auxiliary directory. The problem is that $srcdir (and
102# therefore $ac_aux_dir as well) can be either absolute or relative,
103# depending on how configure is run. This is pretty annoying, since
104# it makes $ac_aux_dir quite unusable in subdirectories: in the top
105# source directory, any form will work fine, but in subdirectories a
106# relative path needs to be adjusted first.
107#
108# $ac_aux_dir/missing
109# fails when called from a subdirectory if $ac_aux_dir is relative
110# $top_srcdir/$ac_aux_dir/missing
111# fails if $ac_aux_dir is absolute,
112# fails when called from a subdirectory in a VPATH build with
113# a relative $ac_aux_dir
114#
115# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
116# are both prefixed by $srcdir. In an in-source build this is usually
117# harmless because $srcdir is `.', but things will broke when you
118# start a VPATH build or use an absolute $srcdir.
119#
120# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
121# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
122# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
123# and then we would define $MISSING as
124# MISSING="\${SHELL} $am_aux_dir/missing"
125# This will work as long as MISSING is not called from configure, because
126# unfortunately $(top_srcdir) has no meaning in configure.
127# However there are other variables, like CC, which are often used in
128# configure, and could therefore not use this "fixed" $ac_aux_dir.
129#
130# Another solution, used here, is to always expand $ac_aux_dir to an
131# absolute PATH. The drawback is that using absolute paths prevent a
132# configured tree to be moved without reconfiguration.
