Here is my Windows 64 bits patch. It is quite crude and only attempts to make it possible to compile
a 64bits emacs with the MS Sdk.
I have sent the paperwork to the FSF last week, so this patch could be reviewed and maybe integrated soon.
It is against emacs-24, current trunk.
Not everything is taken cared of: the heap allocation scheme should probably be reworked. Anyway,
I was able to run an emacs and make it allocate everything available on my Windows 64 machine
(4Gb of Ram + around 10Gb of swap). It just did it without crashing.
Best regards,
Fabrice

Thanks, it will.

Start with bug #9960, where some of this was discussed. Maybe Fabrice
could post the patches he has till now.
