Squeak4.6-15093 is now available at http://ftp.squeak.org/4.6/.  It
addresses the issues we found with RC1.

The sources file was rebuilt again, which means the prior
SqueakV46.sources file should not be trusted.  For that reason, I
actually decided to remove the RC1 files.

Eliot said he wants to build the Cog VM one more time.  Then I'll try
to assemble the All-In-One.
