This fixes configure issues with recent autoconf, e.g:
  autoreconf: Entering directory `Modules/_ctypes/libffi'
  autoreconf: configure.ac: not using Gettext
  autoreconf: running: aclocal --force
  configure.ac:26: error: m4_copy: won't overwrite defined macro: _AC_ARG_VAR_PRECIOUS
  configure.ac:26: the top level

The problem is still present in python-2.6.5 but fixed in python-svn.
