snn.lib , setmode and linker errors

[Charlie]

The following C code works fine ( taken from digitalmars website 
http://www.digitalmars.com/rtl/io.html#_setmode ) :

#include <stdio.h>
#include <io.h>
#include <fcntl.h>

void main ()
{
    int result;
    result = _setmode(_fileno(stdin), _O_BINARY);
    if (result == -1)
       perror("Error setting mode");
    else
       printf("Printer successfully set to text mode\n");
}
