Thou shalt not, in the language of C, under any circumstances, on the
pain of death, declare or define a function with an empty set of
parentheses, for though in the language of C++ it meaneth the same as
(void), in C it meaneth (...) which is of meaningless as there be no
anchor argument by which the types of the varadic arguments can be
expressed, and which misleadeth the compiler into allowing unsavory code
and in some cases generate really ugly stuff for varadic handling.
