AIX 4.3.3 - Undefined Symbols while building STLPort - GCC 3.2.2

[Paul Ruvolo <pruvolo at inviosoftware dot com>]

I am trying to build STLPort on AIX 4.3.3.  I have successfully built 
this package on AIX 5.1 (using GCC 3.2.2 as well).

On both machines I am using the native linker

Aix 4.3.3 -
./gcc -v
Configured with: ../gcc-3.2.2/configure --prefix=/usr/local/fbe/2.0 
--with-stabs --enable-shared --enable-threads=posix --without-gnu-as 
--with-as=/usr/bin/as
Thread mode: aix
gcc version 3.2.2

Aix 5.1 -
./gcc -v
Same as above

When I try to compile STLPort there is a crucial difference between what 
happens on AIX 5.1 and 4.3.3

4.3.3 -
/usr/local/fbe/2.0/bin/g++ -pthread -fexceptions -I../stlport -Wall -W 
-Wno-sign-compare -Wno-unused -Wno-uninitialized -ftemplate-depth-32 
-D_REENTRANT -D__EXTENSIONS__ -O -fPIC dll_main.cpp -c -o 
../lib/obj/GCC-AIX/ReleaseD/dll_main.o

Note: note warning are generated by above step
Alos, I am pretty sure that D_REENTRANT isn't required on AIX, but it is 
there nevertheless.

5.1 -
/usr/local/fbe/2.0/bin/g++ -fexceptions -I../stlport -Wall -W 
-Wno-sign-compare -Wno-unused -Wno-uninitialized -ftemplate-depth-32

Notice all the warning generated.  This turns out to be a good thing 
because I believe this is what is allowing AIX 5.1 to define the 
following symbol, while 4.3.3 fails to do some.

nm -C dll_main.o | grep Node_Alloc
_ZN4_STL16_Node_Alloc_LockILb1ELi0EE7_S_lockE   U   -
_ZN4_STL16_Node_Alloc_LockILb1ELi0EE7_S_lockE   d   83260      4

AIX 5.1 - 
nm -C dll_main.o | grep Node_Alloc
_ZN4_STL16_Node_Alloc_LockILb1Eli0EE7_S_lockE    D   72980
_ZN4_STL16_Node_Alloc_LockILb1Eli0EE7_S_LockE    U   -
_ZN4_STL16_Node_Alloc_LockILb1Eli0EE7_S_LockE    d   83984


When I try to link a helloWorld program on Aix 4.3.3 it fails with the 
following message

ERROR: Undefined symbol: _STL::_Node_Alloc_Lock<(bool)1, (int)0>::_S_lock

A side note is that I installed GNUPro 2.95 to get more information.  
When I compile dll_main.cpp with GNUPro the Node_Alloc symbol is defined 
as expected.  I have other reasons for not wanting to using GNUPro as my 
final choice for compiler, so I need to get GCC 3.2.2 working.

FYI, I applied *APAR* IY26685 to my AIX 4.3.3 system.

I can't seem to nail this down.

Thanks,
Paul
