341     # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
342     # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
343     # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
344     #
345     # Of course, Automake must honor this variable whenever it calls a
346     # tool from the auxiliary directory. The problem is that $srcdir (and
347     # therefore $ac_aux_dir as well) can be either absolute or relative,
348     # depending on how configure is run. This is pretty annoying, since
349     # it makes $ac_aux_dir quite unusable in subdirectories: in the top
350     # source directory, any form will work fine, but in subdirectories a
351     # relative path needs to be adjusted first.
352     #
353     # $ac_aux_dir/missing
354     # fails when called from a subdirectory if $ac_aux_dir is relative
355     # $top_srcdir/$ac_aux_dir/missing
356     # fails if $ac_aux_dir is absolute,
357     # fails when called from a subdirectory in a VPATH build with
358     # a relative $ac_aux_dir
359     #
360     # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
361     # are both prefixed by $srcdir. In an in-source build this is usually
362     # harmless because $srcdir is `.', but things will broke when you
363     # start a VPATH build or use an absolute $srcdir.
364     #
365     # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
366     # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
367     # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
368     # and then we would define $MISSING as
369     # MISSING="\${SHELL} $am_aux_dir/missing"
370     # This will work as long as MISSING is not called from configure, because
371     # unfortunately $(top_srcdir) has no meaning in configure.
372     # However there are other variables, like CC, which are often used in
373     # configure, and could therefore not use this "fixed" $ac_aux_dir.
374     #
375     # Another solution, used here, is to always expand $ac_aux_dir to an
376     # absolute PATH. The drawback is that using absolute paths prevent a
377     # configured tree to be moved without reconfiguration.
