* sysdeps/generic/utmp-equal.h: New file, extracted from utmp_file.c.
* sysdeps/generic/utmp_file.c (setutent_file): Invalidate last_entry also on platforms with !HAVE_UT_TYPE. (proc_utmp_eq): Remove function. (internal_getut_r, pututline_file): Call __utmp_equal instead. 2002-09-20 Bruno Haible <bruno@clisp.org> * abi-tags: Add support for FreeBSD with ABI OS value 3. * elf/cache.c (print_entry): Support the GNU/FreeBSD ABI tag.
