I plan to apply the second patch in the issue, it restores the 1.6 libtool detection and fixes the the --with-experimental-libtool problem.
The code did require maintenance in the past, and may require maintenance in the future, but it hasn't required any maintenance in the last three years on the 1.6 branch. Going back to the code in our current release means that there should not be any libtool related build regressions in 1.7, even on platforms that we don't explicitly test. http://subversion.tigris.org/issues/show_bug.cgi?id=3930 -- uberSVN: Apache Subversion Made Easy http://www.uberSVN.com
