182# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
183# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
184#
185# Of course, Automake must honor this variable whenever it calls a
186# tool from the auxiliary directory.  The problem is that $srcdir (and
187# therefore $ac_aux_dir as well) can be either absolute or relative,
188# depending on how configure is run.  This is pretty annoying, since
189# it makes $ac_aux_dir quite unusable in subdirectories: in the top
190# source directory, any form will work fine, but in subdirectories a
191# relative path needs to be adjusted first.
192#
193# $ac_aux_dir/missing
194#    fails when called from a subdirectory if $ac_aux_dir is relative
195# $top_srcdir/$ac_aux_dir/missing
196#    fails if $ac_aux_dir is absolute,
197#    fails when called from a subdirectory in a VPATH build with
198#          a relative $ac_aux_dir
199#
200# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
201# are both prefixed by $srcdir.  In an in-source build this is usually
202# harmless because $srcdir is `.', but things will broke when you
203# start a VPATH build or use an absolute $srcdir.
204#
205# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
206# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
207#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
208# and then we would define $MISSING as
209#   MISSING="\${SHELL} $am_aux_dir/missing"
210# This will work as long as MISSING is not called from configure, because
211# unfortunately $(top_srcdir) has no meaning in configure.
212# However there are other variables, like CC, which are often used in
213# configure, and could therefore not use this "fixed" $ac_aux_dir.
214#
215# Another solution, used here, is to always expand $ac_aux_dir to an
216# absolute PATH.  The drawback is that using absolute paths prevent a
