It's a hard balance between "most people want to run configure --bootstrap" and "here's a massive wall of text of every detail about building". I think the balance in this change is better than it was before -- most people on Windows don't want to build their own binary. Fixes #983.
In commit v1.1.0^2~15^2~20 (stub out an api and de-constify Pool, 2012-10-03) the Edge "pool_" member was added as a raw pointer but the initializer was accidentally left out of the constructor. Add it now.
