8939 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
8940 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
8941 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
8942 #
8943 # Of course, Automake must honor this variable whenever it calls a
8944 # tool from the auxiliary directory.  The problem is that $srcdir (and
8945 # therefore $ac_aux_dir as well) can be either absolute or relative,
8946 # depending on how configure is run.  This is pretty annoying, since
8947 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
8948 # source directory, any form will work fine, but in subdirectories a
8949 # relative path needs to be adjusted first.
8950 #
8951 # $ac_aux_dir/missing
8952 #    fails when called from a subdirectory if $ac_aux_dir is relative
8953 # $top_srcdir/$ac_aux_dir/missing
8954 #    fails if $ac_aux_dir is absolute,
8955 #    fails when called from a subdirectory in a VPATH build with
8956 #          a relative $ac_aux_dir
8957 #
8958 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
8959 # are both prefixed by $srcdir.  In an in-source build this is usually
8960 # harmless because $srcdir is `.', but things will broke when you
8961 # start a VPATH build or use an absolute $srcdir.
8962 #
8963 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
8964 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
8965 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
8966 # and then we would define $MISSING as
8967 #   MISSING="\${SHELL} $am_aux_dir/missing"
8968 # This will work as long as MISSING is not called from configure, because
8969 # unfortunately $(top_srcdir) has no meaning in configure.
8970 # However there are other variables, like CC, which are often used in
8971 # configure, and could therefore not use this "fixed" $ac_aux_dir.
8972 #
8973 # Another solution, used here, is to always expand $ac_aux_dir to an
8974 # absolute PATH.  The drawback is that using absolute paths prevent a
