Cygwin User's 
Guide  http://www.cygwin.com/cygwin-ug-net/using-textbinary.html says


"The Cygwin system gives us some flexibility in deciding how files are to 
be opened when the mode is not specified explicitly. The rules are 
evolving, this section gives the design goals.


a) If the file appears to reside on a file system that is mounted (i.e. if 
its pathname starts with a directory displayed by mount), then the default 
is specified by the mount flag. If the file is a symbolic link, the mode of 
the target file system applies.

b) If the file appears to reside on a file system that is not mounted (as 
can happen when the path contains a drive letter), the default is text.

.... "


In understand that a windows path ([...] the path contains a drive letter ) 
should be seen as text file.
This not what I experience.
