No, it's not possible. And it won't ever be possible, Walter is dead-set 
against it. If you want to know the history, look waaaay back in the 
forums. This question comes up every so often.

There is a workaround though:

template v(string versionID)
{
    mixin("version(" ~ versionID ~ ") enum v = true; else enum v = false;");
}

static if(v!"X86_64" || v!"X86")
