Nope.

I'm not sure what this "hanging" DLL was.  That is not a symptom
that I heard reported.

The termios.h should be the same as is in the snapshot.  That is
correct.  It was put there so that people wouldn't have to download
the entire snapshot to get this file.

I'm not sure how you came to the conclusion that termios.h would have
something to do with a hanging problem or what correlation you can draw
between kill and termios but I doubt that termios would be the cause of
any application hanging that did not use serial I/O.

If you have an application ghat is using serial I/O then you'll need to
use a recent include/sys/termios.h file when compiling and a recent
libcygwin.a when linking.

If you grep the make source for the string 'termios.h', I think you'll
see that there is no occurrence anywhere.
