 61# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 62# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 63# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 64#
 65# Of course, Automake must honor this variable whenever it calls a
 66# tool from the auxiliary directory.  The problem is that $srcdir (and
 67# therefore $ac_aux_dir as well) can be either absolute or relative,
 68# depending on how configure is run.  This is pretty annoying, since
 69# it makes $ac_aux_dir quite unusable in subdirectories: in the top
 70# source directory, any form will work fine, but in subdirectories a
 71# relative path needs to be adjusted first.
 72#
 73# $ac_aux_dir/missing
 74#    fails when called from a subdirectory if $ac_aux_dir is relative
 75# $top_srcdir/$ac_aux_dir/missing
 76#    fails if $ac_aux_dir is absolute,
 77#    fails when called from a subdirectory in a VPATH build with
 78#          a relative $ac_aux_dir
 79#
 80# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 81# are both prefixed by $srcdir.  In an in-source build this is usually
 82# harmless because $srcdir is `.', but things will broke when you
 83# start a VPATH build or use an absolute $srcdir.
 84#
 85# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 86# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 87#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 88# and then we would define $MISSING as
 89#   MISSING="\${SHELL} $am_aux_dir/missing"
 90# This will work as long as MISSING is not called from configure, because
 91# unfortunately $(top_srcdir) has no meaning in configure.
 92# However there are other variables, like CC, which are often used in
 93# configure, and could therefore not use this "fixed" $ac_aux_dir.
 94#
 95# Another solution, used here, is to always expand $ac_aux_dir to an
 96# absolute PATH.  The drawback is that using absolute paths prevent a
 97# configured tree to be moved without reconfiguration.
