Are you saying that D_LP64 isn't implemented in the current version? 
Because I noticed that it was already listed in the documentation: 
http://www.digitalmars.com/d/1.0/version.html
When I tried to set the D_LP64 version with GDC it said: "Error: version 
identifier 'D_LP64' is reserved and cannot be set" and GDC is quite old 
now. But perhaps it's only reserved and not implemented yet.
