    249 #
    250 # Of course, Automake must honor this variable whenever it calls a
    251 # tool from the auxiliary directory.  The problem is that $srcdir (and
    252 # therefore $ac_aux_dir as well) can be either absolute or relative,
    253 # depending on how configure is run.  This is pretty annoying, since
    254 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
    255 # source directory, any form will work fine, but in subdirectories a
    256 # relative path needs to be adjusted first.

    262 #    fails when called from a subdirectory in a VPATH build with
    263 #          a relative $ac_aux_dir
    264 #
    265 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
    266 # are both prefixed by $srcdir.  In an in-source build this is usually
    267 # harmless because $srcdir is `.', but things will broke when you
    268 # start a VPATH build or use an absolute $srcdir.
    269 #
    270 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
    271 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
    272 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
    273 # and then we would define $MISSING as
    274 #   MISSING="\${SHELL} $am_aux_dir/missing"
    275 # This will work as long as MISSING is not called from configure, because
    276 # unfortunately $(top_srcdir) has no meaning in configure.
    277 # However there are other variables, like CC, which are often used in
    278 # configure, and could therefore not use this "fixed" $ac_aux_dir.

    280 # Another solution, used here, is to always expand $ac_aux_dir to an
