     69 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
     70 #
     71 # Of course, Automake must honor this variable whenever it calls a
     72 # tool from the auxiliary directory.  The problem is that $srcdir (and
     73 # therefore $ac_aux_dir as well) can be either absolute or relative,
     74 # depending on how configure is run.  This is pretty annoying, since
     75 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
     76 # source directory, any form will work fine, but in subdirectories a
     77 # relative path needs to be adjusted first.
     78 #
     79 # $ac_aux_dir/missing
     80 #    fails when called from a subdirectory if $ac_aux_dir is relative
     81 # $top_srcdir/$ac_aux_dir/missing
     82 #    fails if $ac_aux_dir is absolute,
     83 #    fails when called from a subdirectory in a VPATH build with
     84 #          a relative $ac_aux_dir
     85 #
     86 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
     87 # are both prefixed by $srcdir.  In an in-source build this is usually
     88 # harmless because $srcdir is '.', but things will broke when you
     89 # start a VPATH build or use an absolute $srcdir.
     90 #
     91 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
     92 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
     93 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
     94 # and then we would define $MISSING as
     95 #   MISSING="\${SHELL} $am_aux_dir/missing"
     96 # This will work as long as MISSING is not called from configure, because
     97 # unfortunately $(top_srcdir) has no meaning in configure.
     98 # However there are other variables, like CC, which are often used in
     99 # configure, and could therefore not use this "fixed" $ac_aux_dir.
    100 #
    101 # Another solution, used here, is to always expand $ac_aux_dir to an
    102 # absolute PATH.  The drawback is that using absolute paths prevent a
