  Gnulib module: stat
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{stat} may not correctly
  report the size of files or block devices larger than 2 GB.
  (Cf. @code{AC_SYS_LARGEFILE}.)
  @item
  On Linux/x86 and Linux/x86_64, applications compiled in 32-bit mode cannot
  access files that happen to have a 64-bit inode number.  This can occur with
  file systems such as XFS (typically on large disks) and NFS.
  (Cf. @code{AC_SYS_LARGEFILE}.)
  @item
  The @code{st_atime}, @code{st_ctime}, @code{st_mtime} fields are affected by
  the current time zone and by the DST flag of the current time zone on some
  platforms:
  mingw, MSVC 14 (when the environment variable @code{TZ} is set).
  @item
  On MSVC 14, this function fails with error @code{ENOENT}
  on files such as @samp{C:\pagefile.sys} and
  on directories such as @samp{C:\System Volume Information}.
  @item
  On some platforms, @code{stat("link-to-file/",buf)} succeeds instead
  of failing with @code{ENOTDIR}.
  macOS 11.1, FreeBSD 7.2, AIX 7.1, Solaris 9, mingw64.
  @item
  On some platforms, @code{stat(".",buf)} and @code{stat("./",buf)} give
  different results:
  mingw, MSVC 14.
  @item
  On Solaris 11.4, when this function yields a timestamp with a
  nonpositive @code{tv_sec} value, @code{tv_nsec} might be in the range
  @minus{}1000000000..@minus{}1, representing a negative nanoseconds
  offset from @code{tv_sec}.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  @xref{sys/stat.h}, for general portability problems with @code{struct stat}.
  @item
  Cygwin's @code{stat} function sometimes sets @code{errno} to @code{EACCES} when
  @code{ENOENT} would be more appropriate.
  @item
  Because of the definition of @code{struct stat}, it is not possible to
  portably replace @code{stat} via an object-like macro.  Therefore,
  expressions such as @code{(islnk ? lstat : stat) (name, buf)} are not
  portable, and should instead be written @code{islnk ? lstat (name,
  buf) : stat (name, buf)}.
  @end itemize
