When running your test program on windows 10 I see a bunch of status word mismatches but no value mismatches.
It's because wine's tests are using different x87 cw. You can see similar value mismatches after setting cw to 0x9001f.
Indeed. I get identical results between msvcrt and ucrtbase if I use 24-bit or 64-bit precision; only 53-bit precision shows a difference.
