1555	When BOOST_HASH_NO_EXTENSIONS is defined hash doesn't support boost::system::error_code	Daniel James	Daniel James	"std::hash supports std::error_code so boost::hash should support boost::system::error_code. Boost.System defined 'hash_value' so when BOOST_HASH_NO_EXTENSIONS is not defined it does, but when BOOST_HASH_NO_EXTENSIONS is defined an explicit specialization is needed. Documentation should be added as well.

I'd actually prefer not to do this as it would mean either declaring boost::system::error_code myself or adding a dependency on Boost.System. Neither of which is desirable.

The other solution would be to remove support for the BOOST_HASH_NO_EXTENSIONS macro. Or to just note the problem."	Bugs	closed	Boost 1.37.0	hash	Boost 1.34.1	Problem	wontfix
