tnurnberg@sin.intern.azundris.com 8dd4751be9 Bug #10776: Failure to compile ndb ReadNodesConf.cpp on AIX 5.2 
mysqld hasn't been built on AIX with ndb-everything in quite a while.
this allowed a variety of changes to be added that broke the AIX build
for both the GNU and IBM compilers (but the IBM suite in particular).
Changeset lets build to complete on AIX 5.2 for users of the GNU and
the IBM suite both. Tudo bem?

/* ***************************************************
FLEXHAMMER
Hammer ndb with read, insert, update and delete transactions.
Arguments:
-t Number of threads to start, default 1
-o Number of operations per hammering-round, default 500
-l Number of loops to run, default 1, 0=infinite
-a Number of attributes, default 25
-c Number of tables, default 1
-s Size of each attribute, default 1
-simple Use simple read to read from database
-dirty Use dirty read to read from database
-write Use writeTuple to write to db
-r Number of records to Hammer
-no_table_create Don't create tables in db
-regulate To be able to regulate the load flexHammer produces.
-stdtables Use standard table names
-sleep Sleep a number of seconds before running the test, this
can be used so that another flexProgram have tome to create tables
Returns:
0 - Test passed
-1 - Test failed
1 - Invalid arguments
Revision history:
1.7 020208 epesson: Adapted to use NDBT
1.10 020222 epesson: Finalised handling of thread results
1.11 020222 epesson: Bug in checking results during delete fixed
