By default Windows opens file in text mode, while a POSIX compliant
implementation treats text files and binary files the same.

The fopen() 'mode' string can include the letter 'b' to indicate
binary mode shall be used. POSIX spec says the character 'b' shall
have no effect, but is allowed for ISO C standard conformance.
Let's add the letter 'b' which works on both POSIX and Windows.
