41     # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
42     # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
43     # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
44     #
45     # Of course, Automake must honor this variable whenever it calls a
46     # tool from the auxiliary directory. The problem is that $srcdir (and
47     # therefore $ac_aux_dir as well) can be either absolute or relative,
48     # depending on how configure is run. This is pretty annoying, since
49     # it makes $ac_aux_dir quite unusable in subdirectories: in the top
50     # source directory, any form will work fine, but in subdirectories a
51     # relative path needs to be adjusted first.
52     #
53     # $ac_aux_dir/missing
54     # fails when called from a subdirectory if $ac_aux_dir is relative
55     # $top_srcdir/$ac_aux_dir/missing
56     # fails if $ac_aux_dir is absolute,
57     # fails when called from a subdirectory in a VPATH build with
58     # a relative $ac_aux_dir
59     #
60     # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
61     # are both prefixed by $srcdir. In an in-source build this is usually
62     # harmless because $srcdir is `.', but things will broke when you
63     # start a VPATH build or use an absolute $srcdir.
64     #
65     # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
66     # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
67     # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
68     # and then we would define $MISSING as
69     # MISSING="\${SHELL} $am_aux_dir/missing"
70     # This will work as long as MISSING is not called from configure, because
71     # unfortunately $(top_srcdir) has no meaning in configure.
72     # However there are other variables, like CC, which are often used in
73     # configure, and could therefore not use this "fixed" $ac_aux_dir.
74     #
75     # Another solution, used here, is to always expand $ac_aux_dir to an
76     # absolute PATH. The drawback is that using absolute paths prevent a
77     # configured tree to be moved without reconfiguration.
