Sorry, nope:

Wrong.

Again the x86_64 thing is due to things which consider - to be a 
seperator (eg GNU arch-system-os type names, package management 
systems) or simple conventions which prefer _ to - (eg CPP defines, - 
might have been special to cpp at some point).

Sigh..

Again:

x86-64: An *ABI*, worked out by AMD and various toolchain people

AMD64 and EMT64: two very similar but still different architectures 
which both support the x86-64 'userspace' ABI.

They are *ALL* valid terms, each describing a *different* thing.

sigh. I happen to work for an industry vendor who produces AMD64 
boxes and maintains a port of an OS to both EMT64 and AMD64, along 
with x86-64 userspace support.. I'm well aware of how the terminology 
is used in the industry, thank you very much.

Well then exactly what was your 'namespace collision' point about 
then?

Actually, dont bother answering that, cause to avoid getting back 
into endless and pointless arguments with you you're going back in my 
kill file.

*plonk*
