This isn't a bug in Asio, so that's the wrong fix (I think). The fix
belongs in Boost.Range, and fixing it there will save this kind of
heartache for many more people.

Thomas, Andrey: Can one of you apply the following patch to libs/range
and tell me if pion compiles successfully with it. (I've been
unsuccessful configuring pion myself.)

Andrey, if you can test this, be sure to revert your change to Asio first.

Thanks,
Eric
