Wipe out older versions in cygwin/latest, cygwin/contrib

[Christopher Faylor]

Our connection to sources.redhat.com is really getting swamped lately
and it is all Cygwin's fault.

When I look at what people are downloading, I see:

/pub/cygwin/latest/gcc/gcc-2.95.2-3-src.tar.gz

a lot.

I don't know why this is, but I do know how to fix it -- I'll delete
the file.

Is there really any reason to keep obsolete tarballs that are several
months old?  I can't think of any.

Unless someone has a good reason for keeping these, I'm going to
start deleting them.
