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")
