function pointer assignment warnings in VC2005

The latest Micrsoft compilers complain when a function is
assigned to a function pointer, and the function's argument
list does not match the prototype precisely.
It was evem complaining about the difference between this:
     int x()
     {
        [...]
     }
and a prototype of
     int x(void);
when assigning that function's address to a function pointer.

This quiets those warnings, without suppressing the mismatch
check altogether for more serious mismatches.
