failed to build libpq.so on AIX 4 and 5/I have a solution

I'm posting this report to pgsql-bugs(at)postgresql(dot)org too. I aware the fact
that I posted mostly the same report to pgsql-bugs(at)postgresql(dot)org about two
month ago. Though, I had a mistake on it. I needed -Wl, before -bnoentry
to support gcc.

System Configuration
---------------------
Architecture (example: Intel Pentium) : any model of RS/6000

Operating System (example: Linux 2.0.26 ELF) : AIX 4.3.3 or later

PostgreSQL version (example: PostgreSQL-7.2.1): PostgreSQL-7.2.1

Compiler used (example: gcc 2.95.2) : gcc 2.9

Please enter a FULL description of your problem:
------------------------------------------------
I tried to build PostgreSQL on AIX 4 and 5 but failed to build libpq.so.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
./configure --enable-multibyte=EUC_JP --with-CC=gcc
make

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
You need to specify -bnoentry option for ld when you build shared library,
on AIX 4 or later. Here is a patch. This works for xlc too.
