Addressed missing function prototype warnings.

In C, a function that accepts no arguments should have a (void)
parameter list in its prototype, not an empty () one.  While they are
equivalent in C++, they are not the same in C.  This patch set address
missing prototype related warnings in C code that uses the functions
in question.
