This of course doesn't have anything to do with your patch, but it caught my eye. reinterpret_casting 0 to void* is not guaranteed to yield a null pointer. :-)
Shortly after this message this message hit the Boost list (and before I saw it), I received this helpful little note from a friend:
"You might want to arm yourself with 5.2.10/8 and 4.10/1."
He's right, I think. 0 is the null pointer constant, which is a null pointer value, which is converted to the null pointer value of the destination type.
He is right, but not because of 5.2.10/8. :-) 5.2.10/5 + footnote 64 say you are home free.
But if you don't agree, I'm just as happy replacing it with a static_cast instead of starting a long discussion.
Your choice. :-)
