There's a bug in the emplace_hint implementation for unordered
containers with equivalent keys. Since my tests missed it, I'm just
going to use the normal emplace implementation until I write better
tests.
[SVN r57005]
- More template use, less preprocessor use.
- Removed some of the Visual C++ 6 workarounds.
- Reduced memory use of the main object.
- Split into smaller headers.
