Compile Errors, 8.1.4 On Solaris 8 x86

To Whom It May Concern:

I'm having some difficulty getting this to compile on a Solaris 8 x86
platform. I noticed Solaris 10 x86 in the supported column, so this is
likely being addressed to the wrong people. configure options were
--with-perl --enable-thread-safety. Quite honestly I'm lost with the
interfaces/libpq and suspect that this is a library issue, though I'm not
sure exactly which ones. I've installed everything I seen in the INSTALL
file and updated it to the latest available on the sunfreeware.com website.
gcc 3.4.2 and libtool 1.5 are installed. the environment variable
LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/opt/sfw/lib:/usr/local/pgsql/lib is
set. What more can I be missing?

TIA,
Guy
