Undefined: basic_streambuff:seekoff

[David Kramer <david@thekramers.net>]

Background: 
*STILL* trying to get a working GNU toolchain on AIX 5.2.  
Currently have:
- gcc 3.3.3 downloaded binary compiled for AIX 5.1
- gcc 3.4.0 bootstrapped from gcc 3.3.3 above
- binutils 2.14 someone else built.  Has architecture problems,
  etc.  See previous messages for that mess.  Never resolved.
- binutils 2.15 I built with gcc 3.3.3 above.  Same problems.
- xlC native AIX compiler
- ld native AIX linker

Problem: Trying to get gcc3.4.0 to compile a tiny little test program,
which includes <sstream> for stringstream operations, and a Rogue Wave
RWCString.  I'm using the native linker.  Even if I comment out the
RWCString in the source code, so there are no references at all to Rogue
Wave in the source, but I still include the -ltls77-xsd on the command
line, I get:

-----------------------------------------------------
~/build/test> g++ -mcpu=rs64a -L/dkramer/build/rogue/lib/ 
-I/dkramer/build/rogue/rogue -D_RWCONFIG=xsd -DRW_NO_LEADING_UNDERSCORE 
-ltls77-xsd -o piddlerw piddlerw.cpp && ./piddlerw

ld: 0711-317 ERROR: Undefined symbol: std::basic_streambuf<char, 
std::char_traits<char> >::seekoff(long, std::_Ios_Seekdir, 
std::_Ios_Openmode)

ld: 0711-317 ERROR: Undefined symbol: .std::basic_ostream<char,

ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more 
information.
collect2: ld returned 8 exit status
-----------------------------------------------------

However, if I try the exact same thing with the gcc 3.3.3 compiler, even 
with the Rogue Wave RWCString uncommented, it compiles and runs fine.

I've STFW and found a few other people who have gotten the same error, but 
no answers on how to solve the problem. I also searched the Rogue Wave 
knowledgebase to no avail. I am assuming there was some sort of change to 
the standard c++ library, but I'm kinda new at this stuff, and could use 
some help.

Thanks in advance.
