I'd rather suppose that the way the path is specified has an influence
on whether files are opened in binary mode or in text mode.  (If I
recall it right, you can specify whether file systems are in `binary
mode' or in `non-binary mode').  Maybe this setting is different for
different paths.

There's also a CYGWIN (or CYGWIN32) environment variable which allows
you to change the way files are opened (look for `binmode' and
`nobinmode').  If you find that changing this setting has any
influence on DDD, I'll be glad to make an appropriate note in one of
the DDD README files.

Of course, if anyone can suggest fixes to the DDD source code such
that such workarounds are no longer necessary, I'll be happy to
implement them.

Greetings,

Andreas
