Build failures using unordered and Sun 5.12 compiler

#include <boost/unordered/unordered_map.hpp>

int main(int argc, char *argv[])
{
        return 0;
}

Yields

"../boost_1_55_0/boost/unordered/detail/allocate.hpp", line 908: Error: Templates can only declare classes or functions.
"../boost_1_55_0/boost/unordered/detail/allocate.hpp", line 908: Error: Templates can only declare classes or functions.

Looks like the scoping of the length template is wrong:
