Status of ayacc and aflex?

["Peter C. Chapin" <pcc482719@gmail.com>]

I have a need for a parser generator and a lexical analyzer generator
that produce Ada. I see that there is an ayacc and aflex project. The
main page for it appears to be here:

   http://www.ics.uci.edu/~arcadia/Aflex-Ayacc/aflex-ayacc.html

However the download link on that page does not appear to work. It seems
like the host no longer exists. Most other references to ayacc point to
the same non-existent place. I was able to locate the source code for a
slightly older version of ayacc on the TenDRA site. I have not yet
located aflex at all.

Is this project completely dead and buried? Is there some other parser
generator that I should be looking at instead?

Thanks in advance for any help you might be able to give...

Peter
