CAST(string_argument AS UNSIGNED) didn't work for big integers above the signed range. (Bug #7036)
Produce warnings of wrong cast of strings to signed/unsigned. Don't block not resolved IP's if DNS server is down (Bug #8467) Fix compiler problems with MinGW (Bug #8872) configure.in: Fix compiler problems with MinGW (Bug #8872) include/config-win.h: Fix compiler problems with MinGW (Bug #8872) include/my_global.h: Fix compiler problems with MinGW (Bug #8872) mysql-test/r/cast.result: Test for cast to signed/unsigned outside of range (Bug #7036) mysql-test/t/cast.test: Test for cast to signed/unsigned outside of range (Bug #7036) mysys/default.c: Cleanup (combine identical code). Done mainly by Jani sql/field.h: Added cast_to_int_type() to ensure that enums are casted as numbers sql/hostname.cc: Don't block not resolved IP's if DNS server is down (Bug #8467) sql/item.h: Added cast_to_int_type() to ensure that enums are casted as numbers sql/item_func.cc: CAST(string_argument AS UNSIGNED) didn't work for big integers above the signed range. (Bug #7036) Produce warnings of wrong cast of strings to signed/unsigned sql/item_func.h: CAST(string_argument AS UNSIGNED) didn't work for big integers above the signed range. (Bug #7036)
