copyright questions

[Leo Brewin <leo.brewin@internode.on.net>]

Greetings,

I have ported some parts of Lapack & Blas to Ada2012 and I'd like to make the code available for public use. But before I release the code I'd like to canvas your opinions on how I should assign the copyright. The original copyright licence (from the Fortran sources) must be included, that much is clear. But I have made some small changes forced upon me by the transition from Fortran to Ada. Do I need to add a separate copyright notice to this Ada version? 

I don't want to get into the debate about the right and wrongs of the various copyright licences (GPL vs. BSD) or the politics of copyright law. I just want to ensure that no third parties can later claim copyright of my work (as limited as it is, it's just a port of the hard work of the original Lapack & Blas team, so there is little intellectual content in my contribution). If someone could point me to an example (of a copyright license for a ported code) that would be a start.

Just to be clear, this is a port to Ada, not a set of bindings to the Fortran code.

Cheers,
Leo
