7028 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
7029 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
7030 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
7031 #
7032 # Of course, Automake must honor this variable whenever it calls a
7033 # tool from the auxiliary directory.  The problem is that $srcdir (and
7034 # therefore $ac_aux_dir as well) can be either absolute or relative,
7035 # depending on how configure is run.  This is pretty annoying, since
7036 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
7037 # source directory, any form will work fine, but in subdirectories a
7038 # relative path needs to be adjusted first.
7039 #
7040 # $ac_aux_dir/missing
7041 #    fails when called from a subdirectory if $ac_aux_dir is relative
7042 # $top_srcdir/$ac_aux_dir/missing
7043 #    fails if $ac_aux_dir is absolute,
7044 #    fails when called from a subdirectory in a VPATH build with
7045 #          a relative $ac_aux_dir
7046 #
7047 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
7048 # are both prefixed by $srcdir.  In an in-source build this is usually
7049 # harmless because $srcdir is `.', but things will broke when you
7050 # start a VPATH build or use an absolute $srcdir.
7051 #
7052 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
7053 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
7054 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
7055 # and then we would define $MISSING as
7056 #   MISSING="\${SHELL} $am_aux_dir/missing"
7057 # This will work as long as MISSING is not called from configure, because
7058 # unfortunately $(top_srcdir) has no meaning in configure.
7059 # However there are other variables, like CC, which are often used in
7060 # configure, and could therefore not use this "fixed" $ac_aux_dir.
7061 #
7062 # Another solution, used here, is to always expand $ac_aux_dir to an
7063 # absolute PATH.  The drawback is that using absolute paths prevent a
7064 # configured tree to be moved without reconfiguration.
