So long as the program knows that it is a text file (or that it is going
to treat it as such), then it could just as easily pass some indication of
that to the {f}open() routine.  Given a reliable indication of text/binary
content of a file, cygwin32 could do a fine job of translating line endings
from the native system to the \n termination expectation of the program.

The problem, though, seems to be in getting all the programs to reliably
pass this information to the {f}open() call, so cygwin32 does not know
if the file is binary or not.

Trying to tell which of several likely line endings is used in a file is
not too difficult, once you know it is a text file.  Trying to tell if
it is a text file or a binary file, however, is not nearly so easy.
