No, I know that long double operations will be slower then float :)
The idea is to have ANOTHER distribution, and if someone realy needs high
precision and if speed is not important for him - he will run another build
of engine.
Normal peoples will work on standart version, and for finakl versions, if
someone realy needs it - one could download and use long-double version
