289: # depending on how configure is run. This is pretty annoying, since
290: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
291: # source directory, any form will work fine, but in subdirectories a
292: # relative path needs to be adjusted first.

297: # fails if $ac_aux_dir is absolute,
298: # fails when called from a subdirectory in a VPATH build with
299: # a relative $ac_aux_dir
300: #
301: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
302: # are both prefixed by $srcdir. In an in-source build this is usually
303: # harmless because $srcdir is '.', but things will broke when you
304: # start a VPATH build or use an absolute $srcdir.
305: #
306: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

308: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
