[boost] backward/hash_set (g++ 4.3.0)

I'm testing Boost.Python compilation with the latest g++ 4.3.0
(svn rev 129691). It fails because ext/hash_set is not available.
On 2007-10-18 it was moved to backward/hash_set (gcc svn rev 129442).
The patch below restores the Boost.Python compilation.
Is this an OK adjustment?
Ralf
