I'm having problems with templates and libstdc++ :-{ One example is using
string:
e.g.
  #include <string>
  int main()
  {
    string s("Hello World!");
    return 0;
  }

Using the command "g++ teststring.cpp" gives lots of multiple definitions at
link time (shown below). The same errors result when -fno-implicit-templates
is specified.

Any ideas?
