Merged LMDZ4-dev branch changes r1241:1278 into the trunk
Running trunk and LMDZ4-dev in LMDZOR configuration on local
machine (sequential) and SX8 (4-proc) yields identical results
(restart and restartphy are identical binarily)
Log history from r1241 to r1278 is available by switching to
source:LMDZ4/branches/LMDZ4-dev-20091210
