- Introduce ualarm() function - Make rename() report EISEMPTY on Windows - Always raise EINVAL upon open(O_RDONLY|O_TRUNC) - Add macro so ./configure will detect SOCK_CLOEXEC - Fix O_TRUNC without O_CREAT not working on Windows - Let fcntl(F_SETFL) change O_APPEND status on Windows - Make sure pwrite() / pread() report ESPIPE on sockets - Raise ESPIPE on Windows when pwrite() is used on pipe - Properly compute O_APPEND CreateFile() flags on Windows - Don't require O_DIRECTORY to open directories on Windows - Fix more instances of Windows reporting EISDIR and ENOTDIR - Normalize EFTYPE and EMLINK to ELOOP on NetBSD and FreeBSD - Make unlink() / rmdir() work on read-only files on Windows - Validate UTF-8 on Windows paths to fix bug with overlong NUL - Always print signal name to stderr when crashing due to SIG_DFL - Fix Windows bug where denormalized paths >260 chars didn't work - Block signals on BSDs when thread exits before trashing its own stack
