Solaris 9 and PgSQL 8.1.3 - createdb Link Fails

I have been unable to get PostreSQL 8.1.3 to compile on Solaris 9.
Thinking this might be a problem with the compile, I have tried GCC
3.3, GCC 3.4.3, and Sun Workshop Compiler 5.0. All three error while
trying to link the createdb binary. I'm configuring GCC builds using:

    ./configure --prefix=/usr/local/postgres-8.1.3 --without-readline

and Sun Workshop builds using:

    ./configure CC=/opt/SUNWspro/bin/cc --prefix=/usr/local/
postgres-8.1.3 --without-readline

A GCC build yields the following errors....

I've done several searches to try and find info about this, but the
only hits on createdb that I find are related to using it, not
getting it to build. I'll try downloading an older release of
PostgreSQL to see if that changes the behavior. Any suggestions would
be greatly appreciated.
