Portability problems not fixed by Gnulib:

  * This function is missing on some platforms: NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, OSF/1 5.1, Solaris 2.4, Cygwin, mingw, Interix 3.5, BeOS.

  * On platforms where off_t is a 32-bit type, this function may not work correctly on files larger than 2 GB.  The fix is to use the AC_SYS_LARGEFILE macro.
