316     # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
317     # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
318     # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
319     #
320     # Of course, Automake must honor this variable whenever it calls a
321     # tool from the auxiliary directory. The problem is that $srcdir (and
322     # therefore $ac_aux_dir as well) can be either absolute or relative,
323     # depending on how configure is run. This is pretty annoying, since
324     # it makes $ac_aux_dir quite unusable in subdirectories: in the top
325     # source directory, any form will work fine, but in subdirectories a
326     # relative path needs to be adjusted first.
327     #
328     # $ac_aux_dir/missing
329     # fails when called from a subdirectory if $ac_aux_dir is relative
330     # $top_srcdir/$ac_aux_dir/missing
331     # fails if $ac_aux_dir is absolute,
332     # fails when called from a subdirectory in a VPATH build with
333     # a relative $ac_aux_dir
334     #
335     # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
336     # are both prefixed by $srcdir. In an in-source build this is usually
337     # harmless because $srcdir is `.', but things will broke when you
338     # start a VPATH build or use an absolute $srcdir.
339     #
340     # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
341     # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
342     # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
343     # and then we would define $MISSING as
344     # MISSING="\${SHELL} $am_aux_dir/missing"
345     # This will work as long as MISSING is not called from configure, because
346     # unfortunately $(top_srcdir) has no meaning in configure.
347     # However there are other variables, like CC, which are often used in
348     # configure, and could therefore not use this "fixed" $ac_aux_dir.
349     #
350     # Another solution, used here, is to always expand $ac_aux_dir to an
351     # absolute PATH. The drawback is that using absolute paths prevent a
352     # configured tree to be moved without reconfiguration.
