I would like to point out, that this won't work for srcdir != builddir
as the toplevel directory in a hierarchy is found after the subdirs.
My current aproach (following the basic idea) is to sort the output
after
slashes. If someone has a better idea, let me know.

The current code looks like this:

# I consider the following a bad hack. But I couldn't come up with a
# solution without case. If someone has, let me know
# The Makefiles have to be sorted for slashes, since configure creates
# only one directory per Makefile not the whole hierarchy
configure.in: configure.in.in subdirs
        @mfs=`find . -name Makefile.am -print | sed -e "s#\.am##" | sed
-e "s#\./##" | sort -r`; \
        maxslashes=1; \
        for i in $$mfs; do \
          slashes=`echo $$i | sed -e "s#[^/]##g" | wc -c | sed
"s#[^0123456789]##g"`; \ 
          case "$$slashes" in \
          1) list_1="$$list_1 $$i";;\
          2) list_2="$$list_2 $$i";;\
          3) list_3="$$list_3 $$i";;\
          4) list_4="$$list_4 $$i";;\
          5) list_5="$$list_5 $$i";;\
          6) list_6="$$list_6 $$i";;\
          *) list_big="$$list_big $$i";;\
         esac ;\
        done ;\
        cp -f configure.in.in configure.in ;\
        for i in $$list_big $$list_6 $$list_5 $$list_4 $$list_3 \
                $$list_2 $$list_1; do \   
        sed -e "s#AC_OUTPUT(#AC_OUTPUT($$i #" configure.in >
configure.in.new \
         && mv configure.in.new configure.in ;\
        done
