Re: bison'd files don't compile under Microsoft VC++

[David Gluss]

I wouldn't be interested in bison outputting real C++...then you
couldn't use it in C programs any more.  The underlying task
is pretty simple after all...implement a state machine...so the
overhead of C++ seems uncalled for.
I am curious as to why you "don't want to walk that tracks"...is
it because you want it not to work, or because you have a better way?
What's the solution for guys like us?  Should we just stay with an old
version/start our own development effort?
I am working on a combined Unix/Windows project, and Bison was
definitely the right answer up until now.
I use Cygwin on MS, and of course any update you do to Bison goes
straight into the stream, and then I have to go back and patch
each time I download.  Ouch.
