Yes. It's called AMD64 in many places because the 64bit extension of the
x86 ISA was made by AMD and Intel played catch up later. So for instance
on my Core 2 Quad I use the amd64 Linux kernel (2.6.26-1-amd64).

That's also the way I understand it.

Yep. However once we're past this stage there is still a lot of work.
Not scary because it's hard but because of the size of it, fixing types
all over the place:
* long -> LONG when related to the Windows API
* DWORD -> DWORD_PTR when used to pass around pointers
* spec file fixes: long -> ptr
Then there will be the harder issue of getting 64bit and 32bit binaries
to play nice together: a 64bit executable should be able to start a
32bit one and vice versa, and both should talk to the same Wine server.
But yes. With the gcc issue fixed the future looks much brighter.
