oldbison is a collection of early bison parser generator versions which are not in the archives of GNU and sometimes can be found on servers on the internet.
These bison versions are functional because they were used in production versions of the first gcc compiler versions, but need work to get recompiled on modern systems.
These bison versions can be interesting to see source from the beginning of the GNU software development and are easy to read and learn about.
The oldest files available are dated 20 Dec 1986 and mention gcc-1.12.
