This should really just allow arbitrary values at this point, we should
change that. For the time being you could mark it as Propertiery I

It's LGPLv2 or at your option any later versions, and Apache 2 is
compatible with the LGPLv3 at least.

Also that macro is hardly anything covered by copyright law. It's
mostly just a wrapper to create the struct.
