  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  mingw, MSVC 14.
  @item
  On platforms where @code{off_t} is a 32-bit type, this function may not
  work correctly across the entire data range of files larger than 2 GB.
  The fix is to use the @code{AC_SYS_LARGEFILE} macro.
  @item
  To get anonymous memory, on some platforms, you can use the flags
  @code{MAP_ANONYMOUS | MAP_PRIVATE} and @code{-1} instead of a file descriptor;
  on others you have to use a read-only file descriptor of @file{/dev/zero}.
  @item
  On HP-UX, passing a non-NULL first argument, as a hint for the address (even
  without @code{MAP_FIXED}), often causes @code{mmap} to fail.  Better pass NULL
  in this case.
  @item
  On HP-UX, @code{MAP_FIXED} basically never works.  On other platforms, it depends
  on the circumstances whether memory can be returned at a given address.
