// Linux fcntl flag bits ↔ Windows libuv flag bits. `pathOpen()` builds
// `flagsRes` using Linux constants (O_CREAT=0x40, O_EXCL=0x80,
// O_APPEND=0x400). Windows libuv expects different bits (O_CREAT=0x100,
// O_EXCL=0x400, O_APPEND=0x8). Without translation,
// `fs.openSync(path, 0x241 /* L:WRONLY|CREAT|TRUNC */)` is rejected
// with EINVAL because Linux's 0x40 happens to mean O_TEMPORARY on
// Windows — and O_TEMPORARY without O_CREAT is invalid.
