I looked at the svn gcc trunk code and I got lost. If I want to bakcport openmp-3.0 to Ubuntu Intrepid 4.3.1 source code, which part (other than libgomp/ ) should be merged with 4.3.1? https://bugs.launchpad.net/ubuntu/+source/gcc-4.3/+bug/253185 In this bug, the person was also lost when trying to backport openmp 3.0 to gcc-4.3.1 Or are there any volunteers who would like to take over for this job? Thanks! Mark
