Eliot Miranda uploaded a new version of VMMaker to project VM Maker:

==================== Summary ====================

Name: VMMaker.oscog-eem.583
Author: eem
Time: 13 January 2014, 12:05:56.387 pm
UUID: 0be513d3-c984-427f-a0e2-78bea8c85a26
Ancestors: VMMaker.oscog-dtl.582

Allocate more newSpace for the SpurBootstrap launchSaved shortcut
so the interpreter reserve bytes are accomodated.

Fix superclass of VMSqueakV3BytecodeConstants (thanks tty).
