[Vm-dev] changes to Cross headers files

[Takashi Yamamiya]

An image with VMMaker is http://etoys.laptop.org/svn/trunk/vmm/
(olpc-vmm.image and olpc-vmm.changes)

Image side code is http://etoys.laptop.org/svn/trunk/etoys/
(etoys-dev.image and etoys.changes, you might need to update)

But I don't have any code running on Windows...

Cheers,
- Takashi
