        * testsuite/util/testsuite_allocator.h (tracker_allocator::construct):
        Update to C++0x definition using type to construct as template
        parameter.
        (tracker_allocator::destroy): Likewise for type to destroy.
        (uneq_allocator::construct, uneq_allocator::destroy): Likewise.

I updated the various v3 allocators to use the C++0x API last week,
this does the same for the two test allocators.

Tested x86_64-linux, committed to trunk.
