4381: # Of course, Automake must honor this variable whenever it calls a

4384: # depending on how configure is run. This is pretty annoying, since
4385: # it makes $ac_aux_dir quite unusable in subdirectories: in the top

4393: # fails when called from a subdirectory in a VPATH build with
4394: # a relative $ac_aux_dir
4395: #
4396: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
4397: # are both prefixed by $srcdir. In an in-source build this is usually
4398: # harmless because $srcdir is `.', but things will broke when you
4399: # start a VPATH build or use an absolute $srcdir.
4400: #
4401: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
4402: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
4403: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

4409: # configure, and could therefore not use this "fixed" $ac_aux_dir.
4410: #
