(In [3200]) This should clean up the warnings from core.Variant, io.archive.Zip, io.TempFile? and io.vfs.ZipFolder?. However, there are still two warnings in io.archive.Zip which do not give file or line numbers. I'll keep trying to track them down. Refs #919.

Replying to DRK:

However, there are still two warnings in io.archive.Zip which do not give file or line numbers. I'll keep trying to track them down.

I see these in tango/io/archive/Zip.d on Mac OS X with GDC).
