4.0.2 (2026-03-02)

• Fixed segfault on 32bit architecture with enabled. LFS is enabled by default
  now on 32bit architectures.
• Fix crash when passing wrong socketlen in getnameinfo. Thanks to @glondu
• Fix optopt type in posix-getopt (should be int, not char). Thanks to @glondu
• Fix utimes in posix-time2: it now takes separate ~last_access and
  ~last_modification arguments instead of a single Timeval.t. Thanks to @glondu
• Fix Hurd support: errno is a nativeint on Hurd, clock_nanosleep and
  PROCESS_CPUTIME are not available on Hurd. Thanks to @glondu
• Reorganize internal build: all modules moved under modules/ with improved
  cflags handling
