I can't give you a complete answer, but I believe the "rt" mode is 
supposed to open files in "text" mode.  On cygwin, and maybe mingw, this 
makes an attempt at giving consistent results for mixing unix-style LF 
line endings, and DOS-style CR/LF endings (and maybe Mac-style CR 
endings?).  It's one of the little things that often cause trouble in 
porting between *nix and windows - using "rt" is an attempt at easing 
these problems, although it might cause some of its own.

mvh.,
