Ok, I have done that. I posted a patch to the apr dev list
that fixes apr so that it works with autoconf 2.50 and
libtool 1.4. I then built subversion (with the libtool
patch to remove the .libs hacks) and it worked just fine.

That seems to be an ongoing problem. People run something with
the new autoconf, it does not work, they don't bother to investigate,
then they tell other people that autoconf 2.50 has "issues".
Often, it is the project's incorrectly written macros that are
to blame. I had to track down a number of strange quoting
errors while upgrading another package. It was no fun, but
it was also not autoconf's fault.

I don't see that there is any other option. Both autoconf 2.13
and libtool 1.3 have some serious bugs that are currently
worked around in the build system. These workarounds cause
other problems like static builds not working. By upgrading,
we are trading a known set of bugs for a unknown set of bugs.
My take on upgrading build components like this is, the
sooner the better. That gives people more time to build
on strango systems and report any problems they run into.
