This is pretty annoying, since 231# it makes $ac_aux_dir quite unusable in subdirectories: in the top 232# source directory, any form will work fine, but in subdirectories a 233# relative path needs to be adjusted first. 234# 235# $ac_aux_dir/missing 236# fails when called from a subdirectory if $ac_aux_dir is relative 237# $top_srcdir/$ac_aux_dir/missing 238# fails if $ac_aux_dir is absolute, 239# fails when called from a subdirectory in a VPATH build with 240# a relative $ac_aux_dir 241# 242# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 243# are both prefixed by $srcdir.
