Update autogen to 5.5.2.

New in 5.5.2 - February, 2003
* Fixes for FreeBSD weirdisms with sed, dlopen(), and the Guile library
* stash offsets in uintptr_t types so this thing works when
  sizeof(void*) != sizeof(off_t)
* still more configury fixes.  It will never, ever end.

New in 5.5 - December 15, 2002
* The FOR macro will now accept a list of values, as in:
  [= FOR v IN one, "two , part" three =]
* snprintfv-0.99f was fully incorporated, saving 300K of distribution
  space and a lot of configure time.
* The 'dne' function will accept "-d" as the first argument in order
  to suppress the date from the output.

New in 5.4.8 - December 10, 2002
* Freed AutoOpts from libguile.  It was never really dependent.
* new snprintfv library incorporated
