The -w does anyway not work under Unix or Windows. It is not the job
of GnuPG to delete files. That's Unix philosophy.

Secure file deletion is a very tough problem. The only working
solution is to use a filesystem feature. Trying to work around will
give soon trouble when you change the filesystem (e.g. from ext2 to
Reiser): you believe the file is securly deleted but it is not.
