The problem is that $srcdir (and 228# therefore $ac_aux_dir as well) can be either absolute or relative, 229# depending on how configure is run. This is pretty annoying, since 230# it makes $ac_aux_dir quite unusable in subdirectories: in the top 231# source directory, any form will work fine, but in subdirectories a 232# relative path needs to be adjusted first. 233# 234# $ac_aux_dir/missing 235# fails when called from a subdirectory if $ac_aux_dir is relative 236# $top_srcdir/$ac_aux_dir/missing 237# fails if $ac_aux_dir is absolute, 238# fails when called from a subdirectory in a VPATH build with 239# a relative $ac_aux_dir 240# 241# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 242# are both prefixed by $srcdir. In an in-source build this is usually 243# harmless because $srcdir is `.', but things will broke when you 244# start a VPATH build or use an absolute $srcdir. 245# 246# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 247# iff we strip the leading $srcdir from $ac_aux_dir.
