The current development version of INN is now using libtool 1.3.3, which
seems to have native support for -belf both with compiling and linking; I
think it now takes care of this with a libtool build (and it shouldn't
matter for a static build).  I've rolled the UnixWare compiler flag
settings into the host-specific section of our configure script, based on
config.guess output (which has also been updated to libtool 1.3.3).

If you get a chance, could you try a current snapshot from
/isc/inn/snapshots (wait a day so that my latest commits will make it into
the tree) and check that it still compiles correctly on OpenServer and
UnixWare?  Thanks!

Yeah, that's reasonable.  I see that the checks changed between the
version of config.guess that came with autoconf 2.13 and the one that came
with libtool 1.3.3.
