127# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
128# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
129# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
130#
131# Of course, Automake must honor this variable whenever it calls a
132# tool from the auxiliary directory.  The problem is that $srcdir (and
133# therefore $ac_aux_dir as well) can be either absolute or relative,
134# depending on how configure is run.  This is pretty annoying, since
135# it makes $ac_aux_dir quite unusable in subdirectories: in the top
136# source directory, any form will work fine, but in subdirectories a
137# relative path needs to be adjusted first.
138#
139# $ac_aux_dir/missing
140#    fails when called from a subdirectory if $ac_aux_dir is relative
141# $top_srcdir/$ac_aux_dir/missing
142#    fails if $ac_aux_dir is absolute,
143#    fails when called from a subdirectory in a VPATH build with
144#          a relative $ac_aux_dir
145#
146# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
147# are both prefixed by $srcdir.  In an in-source build this is usually
148# harmless because $srcdir is '.', but things will broke when you
149# start a VPATH build or use an absolute $srcdir.
150#
151# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
152# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
153#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
154# and then we would define $MISSING as
155#   MISSING="\${SHELL} $am_aux_dir/missing"
156# This will work as long as MISSING is not called from configure, because
157# unfortunately $(top_srcdir) has no meaning in configure.
158# However there are other variables, like CC, which are often used in
159# configure, and could therefore not use this "fixed" $ac_aux_dir.
160#
161# Another solution, used here, is to always expand $ac_aux_dir to an
162# absolute PATH.  The drawback is that using absolute paths prevent a
163# configured tree to be moved without reconfiguration.
