The problem is that $srcdir (and 98# therefore $ac_aux_dir as well) can be either absolute or relative, 99# depending on how configure is run. This is pretty annoying, since 100# it makes $ac_aux_dir quite unusable in subdirectories: in the top 101# source directory, any form will work fine, but in subdirectories a 102# relative path needs to be adjusted first. 103# 104# $ac_aux_dir/missing 105# fails when called from a subdirectory if $ac_aux_dir is relative 106# $top_srcdir/$ac_aux_dir/missing 107# fails if $ac_aux_dir is absolute, 108# fails when called from a subdirectory in a VPATH build with 109# a relative $ac_aux_dir 110# 111# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 112# are both prefixed by $srcdir. In an in-source build this is usually 113# harmless because $srcdir is '.', but things will broke when you 114# start a VPATH build or use an absolute $srcdir. 115# 116# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 117# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 118# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 119# and then we would define $MISSING as 120# MISSING="\${SHELL} $am_aux_dir/missing" 121# This will work as long as MISSING is not called from configure, because 122# unfortunately $(top_srcdir) has no meaning in configure. 123# However there are other variables, like CC, which are often used in 124# configure, and could therefore not use this "fixed" $ac_aux_dir. 125# 126# Another solution, used here, is to always expand $ac_aux_dir to an 127# absolute PATH.
