If you want the return values of read() match the number of characters you
asked for, you need to open the file in binary mode, using O_BINARY:

     file_fd = open(argv[1], O_RDONLY | O_BINARY);

(The exception is that if your file system is mounted in text=binary mode,
then O_BINARY is the default.)

For text mode opens, read() is stripping out \r's.
