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.

# 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,
206
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
207
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

209
