Sorry, solution above is no longer valid.
Version below works for DMD 2.066 and 2.067 (tested for X86).

void setFileModeBinary(File f, bool setBinary = true)
{
	// extracted from phobos stdio rawWrite
	version(Windows) {
		import std.stdio, std.c.stdlib;
	
		f.flush(); // before changing translation mode
		immutable fd = _fileno(f.getFP);

		if (setBinary) {
			_setmode(fd, _O_BINARY);

			version(CRuntime_DigitalMars) { // D2.067
				import core.atomic;

				// @@@BUG@@@ 4243
				atomicOp!"&="(__fhnd_info[fd], ~FHND_TEXT);
			} else version(DigitalMars) { // D2.066
				version (Win32) {
					import core.atomic;

					// @@@BUG@@@ 4243
					atomicOp!"&="(__fhnd_info[fd], ~FHND_TEXT);
				}
			}
		} else {
			version (MICROSOFT_STDIO) {}
			else {
				enum _O_TEXT   = 0x4000;
			}
	
			_setmode(fd, _O_TEXT);

			version(CRuntime_DigitalMars) { // D2.067
				import core.atomic;
	
				// @@@BUG@@@ 4243
				atomicOp!"&="(__fhnd_info[fd], ~FHND_TEXT);
			} else version(DigitalMars) { // D2.066
				version (Win32) {
					import core.atomic;

					// @@@BUG@@@ 4243
					atomicOp!"|="(__fhnd_info[fd], FHND_TEXT);
				}
			}
		}
	}
}

IMO a function like this belongs in Phobos stdio
