which version of Boost are you using? I don't know if it's fixed now but older
releases (e.g. 1.42) did not support the current rvalue-reference model and
unordered_map has no copy-constructor, only a move constructor:
unordered_map(unordered_map&& other)
With the latest rvalue-reference model that cannot bind to an lvalue.
If you want to use GCC 4.6.0 and -std=c++0x then you need to use a version of
Boost that can handle it.
