Jeremie Salvucci (who is my intern, so we work each working day together) did all the necessary legal work to be authorized to contribute to GCC (see some previous messages for references : he is authorized to commit as student of Université Paris Est [Marne la Vallée] and as intern of CEA -LIST). So Jeremie is already covered by copyright assignment (from CEA) & disclaimer (from Univ Paris Est). Legally as is ok (and this was checked by Paolo). However, he still don't have any ssh account on gcc.gnu.org so he don't not yet have in practice write (after approval) access to the Subversion repository of GCC. What are the concrete steps to get him such an account? It would be much simpler (both for Jeremie & for me Basile) if he [= Jeremie Salvucci] had his own account. For the few patches he already contributed to the MELT branch, I committed them for him. But it would be much simpler for him to have the ability (that is the account) to submit on Gcc's Svn. For practical details (e.g. preferred logins, ssh keys) ask jeremie.salvu...@free.fr Cheers -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basile<at>starynkevitch<dot>net mobile: +33 6 8501 2359 8, rue de la Faiencerie, 92340 Bourg La Reine, France *** opinions {are only mines, sont seulement les miennes} ***
