When compiling with -Wsystem-headers, I noticed:
/usr/include/c++/4.5/bits/hashtable.h:179:30: warning: 'std::_Hashtable<const
void*, const void*, std::allocator<const void*>, std::_Identity<const void*>,
..., ..., std::__detail::_Mod_range_hashing,

false, true, true>::_M_rehash_policy' will be initialized after [-Wreorder]

[-Wreorder]
Moving the initialization of _M_buckets to before _M_bucket_count should fix
it. This is actually the *only* extra warning I got when compiling a large C++
codebase with -Wsystem-headers, which is great!
