184: #
185: # Of course, Automake must honor this variable whenever it calls a
186: # tool from the auxiliary directory. The problem is that $srcdir (and
187: # therefore $ac_aux_dir as well) can be either absolute or relative,
188: # depending on how configure is run. This is pretty annoying, since
189: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
190: # source directory, any form will work fine, but in subdirectories a
191: # relative path needs to be adjusted first.

201: # are both prefixed by $srcdir. In an in-source build this is usually
202: # harmless because $srcdir is `.', but things will broke when you
203: # start a VPATH build or use an absolute $srcdir.
204: #
205: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
