committer: Dmitry Lenev <dlenev@mysql.com>
branch nick: mysql-6.0-3726-w2
timestamp: Wed 2008-06-25 20:28:57 +0400
message:
  Fix build failure of mysql-6.0-3726 tree on Windows.

  The failure was caused by the fact that sql/mdl.cc was
  using __func__ macro without including sql_profile.h
  header which contained definition of this macro for
  those platforms that miss it.

  This patch solves this problem by moving this define to
  include/my_global.h which makes it available in modules
  which don't/can't include sql/mysql_priv.h.

This is a patch that is part of WL#3726.

include/my_global.h:
  Moved definition of __func__ macro from sql/sql_profile.h to
  include/my_global.h to make it accessible from those modules
  of the server which don't include mysql_priv.h.
sql/sql_profile.cc:
  Removed _unknown_func_ const variable since it is no longer used
  by __func__ macro.
sql/sql_profile.h:
  Moved definition of __func__ macro from sql/sql_profile.h to
  include/my_global.h to make it accessible from those modules
  of the server which don't include mysql_priv.h.
