An anonymous user was kind to compile a list of easy to close bugs.
Don’t let this effort be unhonored and close as many of them as possible
In any case please remove those closed items from the wiki.
If you do not have the permissions to close a bug on Savannah, write the a comment:
CODE SPRINT: This item was open for a long time and no further progress is to be expected. Thus it will be closed now. If you care for this bug or you think it was a wrong decision, please write details for your argument and it can be reopened again.
And @siko1056 or someone else will take care of closing it.
