Feature-test macro (renamed from the original proposal by cplusplus/draft@05e8bbe, thanks S. B. Tam (@cpplearner) 😻 ):

#define __cpp_lib_algorithm_default_value_type 202603L

Feature-test macro (expected - ⚠️ WG21 editors have raised concerns about its length and it may be renamed ⚠️):

#define __cpp_lib_default_template_type_for_algorithm_values 202403L

They renamed it to __cpp_lib_algorithm_default_value_type in cplusplus/draft@05e8bbe.
