The problem is that $srcdir (and 100# therefore $ac_aux_dir as well) can be either absolute or relative, 101# depending on how configure is run. This is pretty annoying, since 102# it makes $ac_aux_dir quite unusable in subdirectories: in the top 103# source directory, any form will work fine, but in subdirectories a 104# relative path needs to be adjusted first. 105# 106# $ac_aux_dir/missing 107# fails when called from a subdirectory if $ac_aux_dir is relative 108# $top_srcdir/$ac_aux_dir/missing 109# fails if $ac_aux_dir is absolute, 110# fails when called from a subdirectory in a VPATH build with 111# a relative $ac_aux_dir 112# 113# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 114# are both prefixed by $srcdir. In an in-source build this is usually 115# harmless because $srcdir is `.', but things will broke when you 116# start a VPATH build or use an absolute $srcdir. 117# 118# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 119# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 120# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 121# and then we would define $MISSING as 122# MISSING="\${SHELL} $am_aux_dir/missing" 123# This will work as long as MISSING is not called from configure, because 124# unfortunately $(top_srcdir) has no meaning in configure. 125# However there are other variables, like CC, which are often used in 126# configure, and could therefore not use this "fixed" $ac_aux_dir. 127# 128# Another solution, used here, is to always expand $ac_aux_dir to an 129# absolute PATH.
