Should I set stdout in BINARY mode, explicitly?

Should I set stdout in BINARY mode, explicitly?

I am writing a fragment where I should dump my data to stdout, both under Windows and *nix:

The superb NAF tool has this portable code already:
Code:#ifdef __MINGW32__
if (_setmode(_fileno(stdout), O_BINARY) == -1) { die("can't set output stream to binary mode\n"); }
#else
if (!freopen(NULL, "wb", stdout)) { die("can't set output stream to binary mode\n"); }
#endifHowever, I need to know whether the *nix part can be omitted as in my current code:

if (TargetSize <= OneMB) {
fwrite(TargetBlock, 1, TargetSize, stdout);
} else {
for (DoOffset = 0; DoOffset+OneMB < TargetSize; DoOffset=DoOffset+OneMB) {
fwrite(TargetBlock+DoOffset, 1, OneMB, stdout);
}
//if (DoOffset+OneMB >= TargetSize) {
fwrite(TargetBlock+DoOffset, 1, TargetSize - DoOffset, stdout);
}
fclose(stdout);
