147# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
148# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
149# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
150#
151# Of course, Automake must honor this variable whenever it calls a
152# tool from the auxiliary directory.  The problem is that $srcdir (and
153# therefore $ac_aux_dir as well) can be either absolute or relative,
154# depending on how configure is run.  This is pretty annoying, since
155# it makes $ac_aux_dir quite unusable in subdirectories: in the top
156# source directory, any form will work fine, but in subdirectories a
157# relative path needs to be adjusted first.
158#
159# $ac_aux_dir/missing
160#    fails when called from a subdirectory if $ac_aux_dir is relative
161# $top_srcdir/$ac_aux_dir/missing
162#    fails if $ac_aux_dir is absolute,
163#    fails when called from a subdirectory in a VPATH build with
164#          a relative $ac_aux_dir
165#
166# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
167# are both prefixed by $srcdir.  In an in-source build this is usually
168# harmless because $srcdir is '.', but things will broke when you
169# start a VPATH build or use an absolute $srcdir.
170#
171# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
172# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
173#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
174# and then we would define $MISSING as
175#   MISSING="\${SHELL} $am_aux_dir/missing"
176# This will work as long as MISSING is not called from configure, because
177# unfortunately $(top_srcdir) has no meaning in configure.
178# However there are other variables, like CC, which are often used in
179# configure, and could therefore not use this "fixed" $ac_aux_dir.
180#
181# Another solution, used here, is to always expand $ac_aux_dir to an
182# absolute PATH.  The drawback is that using absolute paths prevent a
183# configured tree to be moved without reconfiguration.
