349

350
+ The macro `__cpp_lib_freestanding_operator_new` is defined to the
351
+ integer literal `202306L` if all the default versions of the replaceable
352
+ global allocation functions meet the requirements of a hosted
353
+ implementation, and to the integer literal `0` otherwise [[new.delete]].
354
+
355
+ *Recommended practice:* Freestanding implementations should only define
356
+ a macro from `<version>` if the implementation provides the
357
+ corresponding facility in its entirety.
358
+
359
+ *Recommended practice:* A non-hardened implementation should not define
360
+ macros from `<version>` required for hardened implementations.
