[boost] serializing a hash_map (tweaks for gcc-3.3.4/libstdc++-v3)

Had a couple problems serializing a hash map on gcc-3.3.4/gnu 
libstdc++-v3.  Sorry if this is a repeat, I've googled around a bit and 
found nothing.  Here are the tweaks necessary:

1.  BOOST_HAS_HASH is not defined for this stdlib, needs to be turned 
on.
2.  The <hash_map> header itself is not accessible as <hash_map>, it's 
<ext/hash_map>, and
3.  The BOOST_STD_EXTENSION_NAMESPACE in this case is "__gnu_cxx".

I have a patched stdlibcpp3.hpp and serialization/hash_map.hpp if 
somebody wants 'em...

Cheers,
