    345 #
    346 # Of course, Automake must honor this variable whenever it calls a
    347 # tool from the auxiliary directory.  The problem is that $srcdir (and
    348 # therefore $ac_aux_dir as well) can be either absolute or relative,
    349 # depending on how configure is run.  This is pretty annoying, since
    350 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
    351 # source directory, any form will work fine, but in subdirectories a
    352 # relative path needs to be adjusted first.
    353 #
    354 # $ac_aux_dir/missing
    355 #    fails when called from a subdirectory if $ac_aux_dir is relative
    356 # $top_srcdir/$ac_aux_dir/missing
    357 #    fails if $ac_aux_dir is absolute,
    358 #    fails when called from a subdirectory in a VPATH build with
    359 #          a relative $ac_aux_dir
    360 #
    361 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
    362 # are both prefixed by $srcdir.  In an in-source build this is usually
    363 # harmless because $srcdir is '.', but things will broke when you
    364 # start a VPATH build or use an absolute $srcdir.
    365 #
    366 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
    367 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
    368 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
    369 # and then we would define $MISSING as
    370 #   MISSING="\${SHELL} $am_aux_dir/missing"
    371 # This will work as long as MISSING is not called from configure, because
    372 # unfortunately $(top_srcdir) has no meaning in configure.
    373 # However there are other variables, like CC, which are often used in
    374 # configure, and could therefore not use this "fixed" $ac_aux_dir.
    375 #
    376 # Another solution, used here, is to always expand $ac_aux_dir to an
    377 # absolute PATH.  The drawback is that using absolute paths prevent a
