In other projects, it is set to 89# '$srcdir', '$srcdir/..', or '$srcdir/../..'. 90# 91# Of course, Automake must honor this variable whenever it calls a 92# tool from the auxiliary directory. The problem is that $srcdir (and 93# therefore $ac_aux_dir as well) can be either absolute or relative, 94# depending on how configure is run. This is pretty annoying, since 95# it makes $ac_aux_dir quite unusable in subdirectories: in the top 96# source directory, any form will work fine, but in subdirectories a 97# relative path needs to be adjusted first. 98# 99# $ac_aux_dir/missing 100# fails when called from a subdirectory if $ac_aux_dir is relative 101# $top_srcdir/$ac_aux_dir/missing 102# fails if $ac_aux_dir is absolute, 103# fails when called from a subdirectory in a VPATH build with 104# a relative $ac_aux_dir 105# 106# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 107# are both prefixed by $srcdir. In an in-source build this is usually 108# harmless because $srcdir is '.', but things will broke when you 109# start a VPATH build or use an absolute $srcdir. 110# 111# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 112# iff we strip the leading $srcdir from $ac_aux_dir.
