Q37020: QuickC Generates Warning Message "C4071" erroneously

The code below fragment demonstrates a problem with the way the
QuickC environment handles certain prototypes. When compiled inside
the environment at warning level three, the compiler generates the
warning message C4071 "<function name> no prototype given," even
though the function does have a prototype.

Microsoft has confirmed this to be a problem in Version 1.01. We are
researching this problem and will post new information as it becomes
available.

This message appears only with functions of type void with no
parameters. Because you cannot avoid such constructions if you use
indirect recursion, you cannot work around this problem. However, you
can lower the warning level to two and this problem will not occur.

The following sample code demonstrates this problem:

        void a(void);
        void b(void);

        void a(void)
        {
        }

        void b(void)
        {
          a();
        }

        void main(void)
        {
        }
