branch nick: mariadb-5.1
timestamp: Wed 2010-03-10 11:32:14 +0100
message:
  Fix some compiler warnings seen in Buildbot.
  
  Add some extra error output and code cleanup in an attempt to fix/debug
  a rare random testsuite problem in check_warnings, where the exit code
  from mysqltest is somehow corrupted inside mysql-test-run.pl.
