If, by SunOS, you mean Solaris (at least), I've wondered why it doesn't
detect and build shared libraries.  Below is a patch.  The problem
was in build/ltconfig, which tests to see if -KPIC works by compiling
an empty program.  Sun's PRO C compiler issues a warning in this event,
causing conftest.err to be non-empty, and it concludes the system cannot
do shared libraries when it totally can.  I changed the test program
from being an empty one to one that is "int a;".

The only thing about this patch is that ltconfig appears to itself be
an autoconf generated thing, so the patch really needs to be pushd back
to somewhere else to become permanent.  However, it should be good enough
for us OpenLDAP folks for now.
