The situation is different in the DOS/Windows world where a file can
be opened in one of two modes, binary or text. In the binary mode the
system behaves exactly as in UNIX. However in text mode there are
major differences:</para>

format. Unfortunately you may still have some problems with text
mode. First, some of the utilities included with Cygwin do not yet

not work with binary files (input will stop at ^Z, CRs will be
introduced in the output). Second, you will introduce CRs in text
