 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.
