Windows on ARM

[Maurizio Cimadamore]

Hi Manuel,
Windows/ARM is not a combination provided by Oracle.

That said, FFM supports Windows/ARM. So, assuming you can get your hands 
on a build, it will work.

So, in principle, every platform/OS combination should work - sometimes 
they will be supported directly (and Windows/ARM is one such case). 
Other times, you will use the fallback linker, which will be slower, but 
fully functional.

Hope this helps.
