ha_ndbcluster.h: 

  Bug #31956       auto increment bugs in MySQL Cluster: Added utility method and constant for internal prefetch default
ndb_auto_increment.result:
  BitKeeper file /home/marty/MySQL/mysql-5.0-ndb/mysql-test/r/ndb_auto_increment.result
mysqld.cc:
  Bug #25176  	Trying to set ndb_autoincrement_prefetch_sz always fails: Changed pointer to max value
  Bug #31956  	auto increment bugs in MySQL Cluster: Changed meaning of ndb_autoincrement_prefetch_sz to specify prefetch between statements, changed default to 1 (with internal prefetch to at least 32 inside a statement)
ndb_insert.test, ndb_insert.result:
  Moved auto_increment tests to ndb_auto_increment.test
ndb_auto_increment.test:
  BitKeeper file /home/marty/MySQL/mysql-5.0-ndb/mysql-test/t/ndb_auto_increment.test

  Bug #31956       auto increment bugs in MySQL Cluster: Changed meaning of ndb_autoincrement_prefetch_sz to specify prefetch between statements, changed default to 1 (with internal prefetch to at least 32 inside a statement), added handling of updates of pk/unique key with auto_increment
  Bug #32055  	Cluster does not handle auto inc correctly with insert ignore statement
