On AIX 7.2, when invoking "exit 77", we actually exit with 127.  The
"cleanup" function, called via trap, received an incorrect exit
status, something described in Autoconf's doc.
Reported by Bruno Haible.

README.md

This directory contains examples of Bison grammar files, sorted per language.

Several of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience.

These examples come with a README and a Makefile. Not only can they be used to toy with Bison, they can also be starting points for your own grammars.

Please, be sure to read the C examples before looking at the other languages, as these examples are simpler.
