The problem is that $srcdir (and 607# therefore $ac_aux_dir as well) can be either absolute or relative, 608# depending on how configure is run. This is pretty annoying, since 609# it makes $ac_aux_dir quite unusable in subdirectories: in the top 610# source directory, any form will work fine, but in subdirectories a 611# relative path needs to be adjusted first. 612# 613# $ac_aux_dir/missing 614# fails when called from a subdirectory if $ac_aux_dir is relative 615# $top_srcdir/$ac_aux_dir/missing 616# fails if $ac_aux_dir is absolute, 617# fails when called from a subdirectory in a VPATH build with 618# a relative $ac_aux_dir 619# 620# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 621# are both prefixed by $srcdir. In an in-source build this is usually 622# harmless because $srcdir is `.', but things will broke when you 623# start a VPATH build or use an absolute $srcdir. 624# 625# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 626# iff we strip the leading $srcdir from $ac_aux_dir.
