   67 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
   68 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
   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
  103 # configured tree to be moved without reconfiguration.
