[boost] [intrusive] Expected failure markup.

Hello, I would like to ask if the expected failure markup for intrusive could be removed for Tru64/CXX. There are still many failures left, but as this platform has lost it's 'officially supported' boost status the expected failure markup isn't relevant anyway. It would help me a lot in fixing the remaining issues, as it gives a nice overview of what already works and what doesn't. Regards, Markus
