// A test case for the LEMON parser generator.  Run as follows:
//
//     lemon lemon-test01.y && gcc -g lemon-test01.c && ./a.out
//
// This testcase was made obsolete by check-in 7cca80808cef192f on
// 2021-08-17 (associated with Forum Thread 
// https://sqlite.org/forum/forumpost/bd91fd965c9803c4) and no longer
// works.  It is retained for historical reference only.
