# NOTE: For the DROP DATABASE below we need:
#   - disable result log because ER_DB_DROP_RMDIR contains errno, which can be
#     different on different platforms.
#   - expect different error codes, because Windows and UNIX behaves
#     differently (see below).
#
# NOTE: Windows and UNIX behaves differently in this test case:
#
#   - on UNIX when t1.frm is chmoded to 000, it is perfectly deleted
#     by the first DROP DATABASE, but some other files (t1.MYI and t1.MYD) left
#     in the directory. So, we have to explicitly removes them before the
#     second DROP DATABASE.
#
#   - on Windows when t1.frm is chmoded to 000, it is not deleted by the first
#     DROP DATABASE, but all other files in the database directory are deleted.
#     Thus, we have to change the t1.frm permissions again and delete it
#     explicitly before the second DROP DATABASE.
#
# All those differences do not really matter for the idea of this test case:
# checking that if DROP DATABASE failed, the client is Ok.
