[Bug libstdc++/13805] New: undefined symbol when linking libstdc++.a

["walther at caltech dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

This has been reported before but not resolved (#12595). 

When trying to build a shared library with libstdc++ linked in statically (for
self-containment), the symbol std::time_put_w@@GLIBCPP_3.2 is undefined:
//test.cpp
#include<iostream>
void doit()
{
   std::cout << "Hello World!\n";
}
//end test.cpp

g++ -shared -static -v -Wl,-v -o test.so test.cpp

I have reproduced the problem in gcc versions 3.2.2 and 3.3.2. It was not
present in 3.1. I have tried a RedHat 8.0 and a Mandrake 9.2 system. I have
tried bootstrapping the compilers from scratch, also with the previously
suggested --with-pic option - the problem persists. 

In libstdc++.a the symbol time_put_w is versioned, which it did not use to be in
gcc 3.1:
nm /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/libstdc++.a | grep time_put_w
00000000 B _ZN9__gnu_cxx10time_put_wE
00000000 B _ZSt10time_put_w@@GLIBCPP_3.2
         U _ZN9__gnu_cxx10time_put_wE
nm: stubs.o: no symbols

Please help!

Dirk
