https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255374 --- Comment #26 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #25) I found my copy of 13.2-RELEASE and its header is similar in some respects but it instead has: . . . #ifndef _LIBCPP_FORMAT #define _LIBCPP_FORMAT . . . // Enable the contents of the header only when libc++ was built with LIBCXX_ENABLE_INCOMPLETE_FEATURES. #if !defined(_LIBCPP_HAS_NO_INCOMPLETE_FORMAT) . . . #endif // !defined(_LIBCPP_HAS_NO_INCOMPLETE_FORMAT) #endif // _LIBCPP_FORMAT So it looks like there was a reclassification from it being an incomplete-feature in clang 14 to it being an experimental-feature in clang 15. I do not know if FreeBSD has a uniform handling of experimental-status material in its LLVM. It might be that "incomplete feature" is no longer a thing in LLVM --so I'm not sure if the analogous question would even apply now. --=20 You are receiving this mail because: You are on the CC list for the bug.=
