A C++23 test case, ext-floating14.C, encountered warnings about the redefinition of the __bfloat16 type when compiled with default x86 AVX-related options. To resolve this, the test case is now compiled with -mno-avx512bf16 and -mno-avxneconvert, ensuring that the test suite can be built without these specific warnings and passes cleanly.
