I think two preliminary steps must be done before committing: 

- Further testing, especially on the new i7 machines: gcc43 seems to be incompatible, gcc45 seems to work, but gcc44 behavior is unknown to me at this time;
- Maintainer's approval :)


PS : If gcc44 code is also incompatible with the i7 machines, we should maybe go a step further and adopt gcc45 for scientific packages…
