  POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/lstat.html}
  
  Gnulib module: lstat
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{lstat} may not
  correctly report the size of files or block devices 2 GiB and larger.
  @xref{Large File Support}.
  @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.
  @xref{Large File Support}.
  @item
  For symlinks, when the argument ends in a slash, some platforms don't
  dereference the argument:
  Solaris 9.
  @item
  On some platforms, @code{lstat("file/",buf)} succeeds instead of
  failing with @code{ENOTDIR}.
  macOS 11.1, Solaris 9.
  @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}.
  @item
  On Windows platforms (excluding Cygwin), symlinks are not supported, so
  @code{lstat} does not exist.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  @xref{sys/stat.h}, for general portability problems with @code{struct stat}.
  @end itemize
