If I find a program in C (gpl3) and I adapt it to Emacs Lisp what is the situation regarding
authorship/copyright/licence ?
Please elaborate on what you mean by "adapt it to Emacs Lisp".
It is a single file c source game that you can run from the command line and I would like to rewrite it in elisp.
IANAL, but AFAIK rewriting in a completely different programming
language doesn't qualify as "copying", so for all practical purposes
the Lisp code will be yours and yours alone (although referring to the
C implementation as the source of the general idea and the design
would be a Good Thing).
