Hello,

I've got failures when tried to use Boost.Thread on OpenSolaris with SunStudio,
I hadn't got such problems with older versions

The error is:

"./boost/thread/future.hpp", line 422: Error: 
boost::unique_lock<boost::mutex>::operator=(boost::unique_lock<boost::mutex>&) 
is not accessible from 
boost::detail::future_waiter::all_futures_lock::all_futures_lock(std::vector<boost::detail::future_waiter::registered_waiter>&).

It wasn't a problem in older versions of Boost. At least 1.41 worked fine for 
me.
The patch that fixes this issue is attached.

Artyom
