Re: __gnu_cxx::rope: __uninitialized_fill_n_a error

[Jonathan Wakely]

This fixes a lookup failure when using ropes with an allocator
declared outside namespace std, introduced by
http://gcc.gnu.org/ml/libstdc++/2004-07/msg00157.html

        * include/ext/ropeimpl.h (__uninitialized_fill_n_a): Fix using
        declaration.
        * testsuite/ext/rope/5.cc: New.

Tested x86_64-linux, committed to trunk.
