Not a lawyer, but I think if you just port it to another language it is a derived work in GPL and the ported project must also be GPL.

This is correct.

However, if you're completely re-writing each function, I don't know.

I don't think that argument would apply in this case. It would be necessary to start a new project to give it an alternative license.

And more than that, companies that are serious about avoiding litigation will make sure that everyone working on this new project has not even seen the source code for the library with the other license. If someone who has seen the source code provides help, it will only be in the form of advice, not code, to make sure there is no possible argument that the copyright of the original was violated.
