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

969# Fortunately install-sh will honor a STRIPPROG variable, so we
