1019 # therefore $ac_aux_dir as well) can be either absolute or relative,
1020 # depending on how configure is run.  This is pretty annoying, since
1021 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
1022 # source directory, any form will work fine, but in subdirectories a
1023 # relative path needs to be adjusted first.
1024 #
1025 # $ac_aux_dir/missing
1026 #    fails when called from a subdirectory if $ac_aux_dir is relative
1027 # $top_srcdir/$ac_aux_dir/missing
1028 #    fails if $ac_aux_dir is absolute,
1029 #    fails when called from a subdirectory in a VPATH build with
1030 #          a relative $ac_aux_dir
1031 #
1032 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1033 # are both prefixed by $srcdir.  In an in-source build this is usually
1034 # harmless because $srcdir is `.', but things will broke when you
1035 # start a VPATH build or use an absolute $srcdir.
1036 #
1037 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1038 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
1039 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1040 # and then we would define $MISSING as
1041 #   MISSING="\${SHELL} $am_aux_dir/missing"
1042 # This will work as long as MISSING is not called from configure, because
1043 # unfortunately $(top_srcdir) has no meaning in configure.
1044 # However there are other variables, like CC, which are often used in
1045 # configure, and could therefore not use this "fixed" $ac_aux_dir.
1046 #
1047 # Another solution, used here, is to always expand $ac_aux_dir to an
1048 # absolute PATH.  The drawback is that using absolute paths prevent a
1049 # configured tree to be moved without reconfiguration.
