10122 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
10123 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
10124 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
10125 #
10126 # Of course, Automake must honor this variable whenever it calls a
10127 # tool from the auxiliary directory.  The problem is that $srcdir (and
10128 # therefore $ac_aux_dir as well) can be either absolute or relative,
10129 # depending on how configure is run.  This is pretty annoying, since
10130 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
10131 # source directory, any form will work fine, but in subdirectories a
10132 # relative path needs to be adjusted first.
10133 #
10134 # $ac_aux_dir/missing
10135 #    fails when called from a subdirectory if $ac_aux_dir is relative
10136 # $top_srcdir/$ac_aux_dir/missing
10137 #    fails if $ac_aux_dir is absolute,
10138 #    fails when called from a subdirectory in a VPATH build with
10139 #          a relative $ac_aux_dir
10140 #
10141 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
10142 # are both prefixed by $srcdir.  In an in-source build this is usually
10143 # harmless because $srcdir is '.', but things will broke when you
10144 # start a VPATH build or use an absolute $srcdir.
10145 #
10146 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
10147 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
10148 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
10149 # and then we would define $MISSING as
10150 #   MISSING="\${SHELL} $am_aux_dir/missing"
10151 # This will work as long as MISSING is not called from configure, because
10152 # unfortunately $(top_srcdir) has no meaning in configure.
10153 # However there are other variables, like CC, which are often used in
10154 # configure, and could therefore not use this "fixed" $ac_aux_dir.
10155 #
10156 # Another solution, used here, is to always expand $ac_aux_dir to an
10157 # absolute PATH.  The drawback is that using absolute paths prevent a
10158 # configured tree to be moved without reconfiguration.
