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.
