Cannot link hello world with g++ 3.1 under AIX 4.3.3

[George Rogers <grogers at solution-soft dot com>]

I am not able to get a successful link of a "Hello world" program under g++ 3.1
on AIX 4.3.3.  The same program works fine under HPUX 11.00 and Solaris 2.7
(g++ 3.1) and a similar C (not C++) program works fine under AIX 4.3.3.
(I am also able to build gcc/g++ 3.1 using gcc 3.1 under AIX 4.3.3).  Can 
anyone
give me advice on how to fix this problem?

Here is the information on g++, the program, and the link errors
