Is this sort of fast casting still relevant?

I stumbled upon this page while looking for faster ways to cast types between each other (and floor/ceil). The article was written in 2000 and I was wondering if it is still relevant and safe to use.

Nice find. Even provides a download for the source.

I'm not sure what the etiquette is about his code through. There aren't any of the usual licensing headers, does that mean I can just take it and use it in my projects?
Just drop him an email and ask?
