Before this patch `setmode()` was not detected with Cygwin/MSYS, because it's a macro, not a function, and detection is looking for a function. Switching to symbol detection doesn't work because it mis-detects it on BSD systems which features a function with the same name but different functionality and arguments. Fix it by looking for a `_setmode()` function on Cygwin/MSYS, and use it if available. `_setmode()` is recommended over `setmode()` by Windows documentation so use that on Windows too. It seems to be available on all supported compilers, so omit detection. https://learn.microsoft.com/cpp/c-runtime-library/reference/posix-setmode https://learn.microsoft.com/cpp/c-runtime-library/reference/setmode Officially Windows requires argument `_O_BINARY` with an underscore. `O_BINARY` is also supported but bound to conditions. Continue to use it for simplicity. Cygwin supports `O_BINARY` (no underscore). Closes #15169
