After building/installing autoconf-2.59 and automake-1.6.9 into
version-specific directories, I'm able to regenerate the configure
scripts.   Thanks all for the help.

I've noticed a problem with the patch:
   if test "${with_newlib+set}" = set; then
     AC_LIBTOOL_DLOPEN
   fi

The test always succeeds.  When $with_newlib is "yes",
${with_newlib+set} is "set".

If I change this to the old style test
   if test "x$with_newlib" = x; then
     AC_LIBTOOL_DLOPEN
   fi
then it works as expected.

This is weird.  I see the former idiom everywhere in configure.
The tests can't all be failing.
