Since D conditional compilation must always be a valid declaration or 
statement, you cannot do something like this.

The closest you can do is to use mixins, which means you have to write 
everything inside strings.

It has been proposed quite a few times to have a way to enable/disable 
attributes based on a compile-time boolean. But it's never come close to 
getting included.
