This kind of thing is most commonly used in include guards

You can usually just strip that out in D, since the module system
already just works if imported twice.
#ifndef SOME_THING
#define SOME_THING THING *
#endif
Is this equivalent to:
alias thing = void;
alias someThing = thing*;
I'd have to see that in context though to see why they are doing
it... it is probably some kind of platform specific type
definitions.
