A bit of checking gives (gcc 4.1, gentoo Linux) has this assortment.
__amd64 1
__x86_64 1
__LP64__ 1
__x86_64__ 1
__amd64__ 1
_LP64 1
An opeteron machine with gcc 3.4 gives
__x86_64 1
__amd64 1
__LP64__ 1
__k8 1
__x86_64__ 1
__k8__ 1
__amd64__ 1
_LP64 1
My personal preference would be __LP64__, but I wonder what Windows
compilers preset (both gcc and native Windows compilers)
