Can't compile psqlodbc on Solaris 8

When I try to compile psqlodbc on Solaris 8, it fails. I'm not sure
what I'm doing wrong.
  gcc version 3.4.0
  GNU libtool 1.4.2
  GNU Make 3.80
  solaris 8 linker on Solaris 8 sparc.

configured with the options - --enable-shared --with-iodbc
--with-odbcinst=/usr/local/etc

errors look like this -
