State-Changed-Why:
    Yes, this is odd. In some way the compiler is right, since
    if no prototype were present, the short would be converted
    to an int. Here, there is a prototype, so the conversion
    does not take place. Thus, something different is happening,
    which is exactly what the documentation of -Wconversion says
    is what it is all about. However, in this case it is clearly
    odd to get a message.
    
    Testcase:
    --------------------------------------
    tmp/g> cat x.c
    void func (short);
    void short_test (void)
    {  short x = 0;
       func(x);
    }
    tmp/g> /home/bangerth/bin/gcc-3.2.1-pre/bin/gcc -Wconversion -c x.c
    x.c: In function `short_test':
    x.c:4: warning: passing arg 1 of `func' with different width due to prototype
