  unsigned number that was quoted. (Bug #12612)

  mysql-test/t/func_equal.test
    1.7 05/10/22 02:03:25 jimw@stripped +9 -0
    Add new regression test

  mysql-test/r/func_equal.result
    1.8 05/10/22 02:03:21 jimw@stripped +9 -0
    Add new results

  sql/item_cmpfunc.cc
    1.204 05/10/22 02:02:50 jimw@stripped +15 -0
    Force comparison to as an INT when evaluating IN() when possible
