A 2 % gain for the past week on my code.

L.S.,
In the past week, changes to GNU Fortran / GCC brought me a 4 minute
gain in a 3.5 hour weather forecast (run 4 times a day on my home
computer - see http://moene.org/~hirlam/)
4 minutes on 210 minutes is ~ 2 % - not bad for such a diverse code.
Without digging deeper in it (for which I have little time) it is
impossible to say what change in the past week "made the difference" (if
even it is just one).
Cheers,
