Compiler Options Macros

These macros control specific compiler features.

_ATL_ALL_WARNINGS	A symbol which enables errors in projects converted from previous versions of ATL.
_ATL_APARTMENT_THREADED	Define if one or more of your objects use apartment threading.
_ATL_CSTRING_EXPLICIT_CONSTRUCTORS	Makes certain CString constructors explicit, preventing any unintentional conversions.
_ATL_ENABLE_PTM_WARNING	Define this macro in order to use C++ standard compliant syntax, which generates the C4867 compiler error when a non standard syntax is used to initialize a pointer to a member function.
_ATL_FREE_THREADED	Define if one or more of your objects use free or neutral threading.
_ATL_MULTI_THREADED	A symbol that indicates the project will have objects that are marked as Both, Free or Neutral. The macro _ATL_FREE_THREADED should be used instead.
_ATL_NO_AUTOMATIC_NAMESPACE	A symbol which prevents the default use of namespace as ATL.
_ATL_NO_COM_SUPPORT	A symbol which prevents COM-related code from being compiled with your project.
ATL_NO_VTABLE	A symbol that prevents the vtable pointer from being initialized in the class's constructor and destructor.
ATL_NOINLINE	A symbol that indicates a function should not be inlined.
_ATL_SINGLE_THREADED	Define if all of your objects use the single threading model.
