Here are a couple of nits I noticed (I haven't read the full
patch in detail -- it's way too long).

It's "1.5 or newer"

AC_OUTPUT defines LTLIBOBJS only since Autoconf 2.54.

The error message added in 2.53 is against direct assignments to LIBOBJS
(i.e. LIBOBJS="$LIBOBJS foo.o" should be replaced by AC_LIBOBJ([foo]))
