(repost) gcc3.1.1 problems under AIX

[Jeff Lee <jeff at cdnorthamerica dot com>]

sorry for the repost, I accidentally sent before finishing...

I successfully compiled gcc3.1.1 under AIX4.3.3 but when I try to 
compile this simple program using g++, I get the following errors:

#include <vector>
#include <string>
using namespace std;

int main()
{
vector<string> a;
a.push_back("Hello world");
}


ld: 0711-317 ERROR: Undefined symbol: .std::basic_string<char, 
std::char_traits<char>, std::allocator<char> 
>::basic_string[in-charge](char const*, std::allocator<char> const&)

std::allocator<char> > const&)
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more

collect2: ld returned 8 exit status

Is this a problem with AIX assembler or linker?  I think it has 
something to do with weak symbols being used by g++ for template 
instantiation.  Has anyone else had this problem?  If so, what did you 
do to fix it?  Any help would be greatly appreciated.
Best Regards,
Jeff
