Thanks Ian - yes, I had completely ignored that piece of patch, or more
likely was looking at the wrong version code and concluded I'd already
applied it. Working with differences between gdc-4.3.4/dev/gcc-4.3.4/gcc
and gdc-4.4.3/dev/gcc4.4.3/gcc can get a tad confusing if you're tired.

I have two outstanding buts of patch where I'm not making much progress.
Between 4.3.4 and 4.4.3, tree-gimple disappeared, and was replaced by
gimple, and tree-nested was radically changed. Do you know much about
those changes?

Thanks
Steve
