>Description:
using either gcc 2.95.3 from NetBSD 1.6.1 or gcc 3.3.3 from NetBSD 2.0_BETA for i386 when the compiler is given the warining option -Wconversion a warning is issued ("warning: passing arg 1 of `some_function' with different width due to prototype") when an argument is typed as short using  an ANSI format. If either K&R format is used, or another type such as int, or long is used, no warning is issued.


>How-To-Repeat:
use cc -Wconversion to compile the following

some_function(short x)
{
    return (x);
}

int main()
{
    short a_variable;

    some_function(a_variable);
}
