gcc-4.4.3.20091222

>Description:
	When compiling with gcc44 or g++44, the compiler driver implicitly
	includes '-L/usr/local/lib/gcc44' but this directory is not part
	of the runtime search path, causing the wrong .so to be loaded.

>How-To-Repeat:

$ cat <<EOF > /tmp/x.C
#include <iostream>
#include <tr1/unordered_set>

typedef std::tr1::unordered_set<int> uset_i;

void print_unordered_set(const uset_i& s)
{
   for(uset_i::const_iterator it = s.begin();
       it != s.end();
       ++it)
   {
      std::cout << *it << " ";
   }
   std::cout << std::endl;
}

int main(void)
{
    uset_i s;

    s.insert(1);
    s.insert(2);
    s.insert(3);
    s.insert(1);
    s.insert(1);

    print_unordered_set(s);
}

>Fix:

The front end drivers should include
'-Wl,-rpath,/usr/local/lib/gcc44/gcc/x86_64-portbld-freebsd8.0/4.4.3/../../..'
or similar to ensure that the same directory is searched at runtime as
at linktime.
