scripts/make_win_bin_dist: BitKeeper file /home/georg/work/mysql/prod/mysql-5.0-win/scripts/make_win_bin_dist client/mysqlbinlog.cc: Fix for cmake build: Cmake doesn't use the VC++ files extra/comp_err.c: fixed windows crash (debug): We can't call DBUG_RETURN after my_end. include/my_dbug.h: added missing empty define for DBUG_LEAVE to prevent precompiler errors when compiling in non_debug mode mysql-test/mysql-test-run.pl: Added support for new cmake release and debug paths. mysql-test/t/system_mysql_db_fix.test: This test requires unix shell script mysql_fix_previleges_tables -> skip under windows mysys/my_seek.c: Fix for windows debug crash. However this solution is bad: we should never call lseek with an invalid file pointer. sql/ha_archive.cc: Fixed windows crash: We need dup in gzdopen to keep the filehandle open, otherwise subsequent calls to mysql_close will fail/crash.
