[Accepted at the November, 2022 meeting.]
The wording for the predefined macro __STDCPP_BFLOAT16_T__ added by P1467 can be interpreted more broadly than was intended.
Proposed resolution (approved by CWG 2022-11-08):
Change in 15.11 [cpp.predefined] paragraph 1 as follows:
__STDCPP_BFLOAT16_T__
Defined as the integer literal 1 if and only if the implementation supports an extended floating-point type with the properties of the typedef-name std::bfloat16_t as described in 6.8.3 [basic.extended.fp].
