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

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

224 # fails if $ac_aux_dir is absolute,
225 # fails when called from a subdirectory in a VPATH build with
226 # a relative $ac_aux_dir
228 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
229 # are both prefixed by $srcdir. In an in-source build this is usually
230 # harmless because $srcdir is `.', but things will broke when you
231 # start a VPATH build or use an absolute $srcdir.
233 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
234 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
235 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
