[SAC] osgeo4w: need some changes to trac files

Hi Alex,

Yes please and thank you. :)

I've not participated on an admin committee before or on servers that
host many projects. The servers I've worked on to date have been
single-project focussed so the repercussions of mistakes didn't have
much reach. So I'm quite willing to go through vetting procedures or
what have you until I know the lay of the land.

best,
