[boost] [intrusive_ptr] Constructor not explicit.

Just wondered why intrusive_ptr(T * p, bool add_ref = true); isn't 
explicit?  The second arg defaults so (using bcc32-5.6.4), an 
intrusive_ptr can be explicitly constructed from a raw ptr.  Is this 
intended when shared_ptr is designed to prevent this?

Cheers
