It would be quite easy to provide your own versions of the others, with the exception of libcmain, which would necessarily require either copying the cygwin code or reverse engineering it. What a court of law would have to say, I dunno, but Cygnus has made their intention pretty clear. > I guess regarding Bison you are talking about the shell code for bison.

No, it is not novel, even if you haven't heard it before. -- - For help on using this list, send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
