However that approach was used. It really looks like an 
alternative to a version OrOr. There are plenty of other examples 
in drutime sources.

Sure at some point there is also the problem of the unix 
standards...Every distribution can choose its own value for the 
flag of this func or that one...which creates complexity in C 
`define`s, but should not in D. There is a problem that is not 
solved.
