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

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.

196 # fails if $ac_aux_dir is absolute,
197 # fails when called from a subdirectory in a VPATH build with
198 # a relative $ac_aux_dir
200 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
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.
205 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

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