Anthony,

Could you please tell me what should be the fix in the "move" method?
Since you have already done that for 1.35.

Yes, but not the one suggested. That constructor is private for a
reason, and does not actually exist. It is a bug in the compiler that
requires it to exist, since it should not be chosen for copying a
temporary. If the optimization setting is low enough that the compiler
tries to call it then you'll get a link error.

I change the move function for thread from boost 1.35 in order to fix
an issue with gcc. I'll see what I can come up with. Please raise a
trac ticket so I don't forget, as I'm rather snowed under right now.

Anthony
