Which tool versions yield working pgsql on SunOS 4.1.4 ?

Hi,

I'm attempting to install PostgreSQL on a SunOS 4.1.4 box.  So far,
I've tried various combinations of gcc 2.95.1,.2,.3, PostgreSQL 7.1.3,
7.0.3, 7.3.  In some cases, gcc won't build. In others, PostgreSQL
won't build.  But in the gcc 2.95.2/pg 7.1.3 case, I've got exactly
the same INITDB problem as Jeff Stevens (post 2002-09-25 09:36:36
PST):  ERROR:  syntax error at line 2658: unexpected token parse
error.

If anyone could point me in the right direction for version
combinations, or how to cure the initdb problem, I would sincerely
appreciate it!

Many thanks,
