I am new to C++ and am puzzled by a standard conversion.  In Lippman
on p. 160 discussing function matching by standard conversion said
that any numeric type would match any numeric type.  I thought this to
be a bad idea and wrote this to test it:
++
#include <stream.h>

void ff( short v )
{
        cout << "In short ff " << v << "\n";
}

main()
{
        int i = 70000;
        ff( i );
}
++
This compiled without warnings with both G++ and cfront 2.0 and silently
truncates the integer.  I could not find anything in Ellis about this.
It is certainly not "value-preserving".  Bug or feature?
