This VMMaker update adds primitiveFileStdioHandles from Cog to the
standard VM (Mantis 7591).

I updated trunk/platforms/Cross/plugins/FilePlugin/sqFilePluginBasicPrims.c
with the necessary patch for Unix/Mac. An additional patch is required for

Andreas, I have attached the patched file for Windows, but have not
tested it. Can you please review and apply it to platforms/win32? Thanks.

I note that the commit notice for sqFilePluginBasicPrims.c has not
yet showed up on the vm-dev list, so possibly something is not running
on the squeakvm.org server?
