Or, do this:

module platform; // Or call it whatever

enum
{
HAS_LP64 = ((void*).sizeof > int.sizeof)
}


Then, in your source:

import platform : HAS_LP64;

static if( HAS_LP64 )
{
    ...
}


I've done this a few times when I had several traits that I wanted to
compile against, and didn't want to have the tests all over the place.
