 Portability problems fixed by Gnulib:
 @itemize
+@item
+This function is missing on some platforms:
+MSVC 9.
+@item
+On platforms where @code{off_t} is a 32-bit type, this function is not
+applicable to arbitrary lengths for files larger than 2 GB.  The fix is to
+use the @code{AC_SYS_LARGEFILE} macro.
