    Don't allow to have functions with empty parameters · e2da88ed

    C doesn't check that calls to functions without parameters honors the
    signature. Thus, it is possible to call a function defined as
    
    void function() {...
    
    with several parameters, or assign it to a pointer to function with any
    type and number of parameters, and the compiler won't complain. To avoid
    this, it is mandatory to put "void" inside the parameter list; so the
    previous function must be written as:
    
    void function(void) {...
    
    This allows the compiler to detect illegal usages and assignments.
