[Vm-dev] All white screen on Arm 32 with commit 71ffd3fc0eb74519e2ddd8ea4de87503e925fa16

[Eliot Miranda]

Hi Bruce,

    thanks for the prompt feedback.  I think I've fixed it.  Alas I can't
run 32-bit binaries on my mac because the Cocoa GUi no longer compiles
under supported MacOS versions.  I should have checked with the simulator.
Please check commit a29dc4bea18c728d40f8b16dfe879642d0410d91

    CogVM sources as per VMMaker.oscog-eem.3146

    InterpreterPrimitives: fix the 64-bit large integer support on 32-bit
platforms.
