86: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

88: # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
89: #
90: # Of course, Automake must honor this variable whenever it calls a
91: # tool from the auxiliary directory. The problem is that $srcdir (and
92: # therefore $ac_aux_dir as well) can be either absolute or relative,
93: # depending on how configure is run. This is pretty annoying, since
94: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
95: # source directory, any form will work fine, but in subdirectories a
96: # relative path needs to be adjusted first.
97: #
98: # $ac_aux_dir/missing
99: # fails when called from a subdirectory if $ac_aux_dir is relative
100: # $top_srcdir/$ac_aux_dir/missing
101: # fails if $ac_aux_dir is absolute,
102: # fails when called from a subdirectory in a VPATH build with
103: # a relative $ac_aux_dir
104: #
105: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
106: # are both prefixed by $srcdir. In an in-source build this is usually
107: # harmless because $srcdir is '.', but things will broke when you
108: # start a VPATH build or use an absolute $srcdir.
109: #
110: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
111: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
112: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
113: # and then we would define $MISSING as
114: # MISSING="\${SHELL} $am_aux_dir/missing"
115: # This will work as long as MISSING is not called from configure, because
116: # unfortunately $(top_srcdir) has no meaning in configure.
117: # However there are other variables, like CC, which are often used in
118: # configure, and could therefore not use this "fixed" $ac_aux_dir.
119: #
120: # Another solution, used here, is to always expand $ac_aux_dir to an
