+       * include/std/complex (complex::complex converting ctor): For C++23
+       use explicit specifier with constant expression.  Explicitly cast
+       both parts to _Tp.
+       (__complex_abs, __complex_arg, __complex_cos, __complex_cosh,
+       __complex_exp, __complex_log, __complex_sin, __complex_sinh,
+       __complex_sqrt, __complex_tan, __complex_tanh, __complex_pow): Add
+       __complex__ _Float{16,32,64,128} and __complex__ decltype(0.0bf16)
+       overloads.
+       (complex<float>::complex converting ctor,
+       complex<double>::complex converting ctor,
+       complex<long double>::complex converting ctor): For C++23 implement
+       as template with explicit specifier with constant expression
+       and explicit casts.
+       (__complex_type): New template.
+       (complex): New partial specialization for types with extended floating
+       point types.
+       (__complex_acos, __complex_asin, __complex_atan, __complex_acosh,
+       __complex_asinh, __complex_atanh): Add __complex__ _Float{16,32,64,128}
+       and __complex__ decltype(0.0bf16) overloads.
+       (__complex_proj): Likewise.  Add template for complex of extended
+       floating point types.
+       * include/bits/cpp_type_traits.h (__is_floating): Specialize for
+       _Float{16,32,64,128} and __gnu_cxx::__bfloat16_t.
+       * testsuite/26_numerics/complex/ext_c++23.cc: New test.

+       * config/os/gnu-linux/os_defines.h (_GLIBCXX_HAVE_FLOAT128_MATH):
+       Uncomment.
+       * include/c_global/cmath (nextafter(_Float16, _Float16)): Make it constexpr.
+       If std::__is_constant_evaluated() call __builtin_nextafterf16.
+       (nextafter(__gnu_cxx::__bfloat16_t, __gnu_cxx::__bfloat16_t)): Similarly
+       but call __builtin_nextafterf16b.
+       * testsuite/26_numerics/headers/cmath/nextafter_c++23.cc (test): Add
+       static assertions to test constexpr nextafter.

        * include/bits/fs_path.h (path::filename()): Fix dangling
