Hi Nicolas,

if we target Cygwin as a build environment, this might be worth noticing:
https://cygwin.com/faq.html#faq.programming.64bitporting

If we (eventually?) target MS Visual Studio (resp. its C compiler), the code
might look different. Not sure.

In the Windows (kernel) code, I noticed the use of typedefs, which we could
also establish in the vm's windows-specific platform code:
https://msdn.microsoft.com/en-us/library/windows/desktop/ff381404(v=vs.85).aspx

I wonder if we could manage to write code that compiles in both Cygwin
64-bit and the (free) MS Visual C/C++ compiler:
https://www.microsoft.com/en-us/download/details.aspx?id=41151

... or maybe MS Visual C/C++ only? It would remove Cygwin as a layer of
indirection between dev tools and execution platform...  *duck-and-run* :-D

Overall, it should be really simple (and cheap?) to setup a Windows dev
environment for VM developers. Maybe for real, maybe in a VirtualBox only.
This helps Eliot and other cross-platform VM developers to debug like they
are doing now.

Best,
Marcel
