Portability problems not fixed by Gnulib:
@itemize
@item
-On Windows platforms (excluding Cygwin), @code{st_ino} is always 0.
-@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)}.
-@item
-On some file systems, @code{st_size} contains bogus information for
-symlinks; use the gnulib module areadlink-with-size for a better way
-to get symlink contents.
