It never hurts to make it explicit. In C, a prototype with empty parens is 
sort of like a "wildcard" that will be consistent with any same-named 
function prototype/definition that actually does give the formal params. 
That's something one would use if s/he (A) didn't know what the real formal 
params were, as in syscalls that take a void* or a char* depending on 
platform, or (B) were too lazy to care ^_^  It's good to just put "void" in 
there to make clear that neither of these is going on.

-Wstrict-prototypes :-)  The warning it gives you is "function declaration 
isn’t a prototype".
