setmode again

[Brian Myers]

Ok, here's the current version I tried:

import std.string;
import std.stdio;
import std.c.windows.windows;

extern (Windows)
alias int function(int,int) setmode_f;

//extern ( C ) int setmode(int,int);

void main(char[][] args)
{
    int O_BINARY = 0x8000;
    setmode_f f;
    HMODULE m = cast(HMODULE) LoadLibraryA(toStringz("msvcrt.dll"));
    f = cast(setmode_f) GetProcAddress(m, toStringz("_setmode"));
    if (f(fileno(stdout), O_BINARY) < 0)
        writefln("setmode failed.");

//    if (setmode(fileno(stdout) ,O_BINARY) < 0)
//        writefln("setmode failed.");
    writef("test line1\r\ntestline2\n");
}

No dice. Still doing CR/LF translation.
