OK.  Note that I have no experience whatsoever with cppunit, so take my
advice with a grain of salt:

OK.  These provide only link paths.  You can either remove them;
removing the build tree only should have the same effect, though.

This sounds wrong to me.  You need a reference to libstdc++.la, so leave
that in.  Should be like this, I think:

dependency_libs=' -lpthread 

Is gccv3.4.2 a typo, BTW?  Sounds like you meant gcc-3.4.2?  Ahh no:
/user/sbhatnag/gcc-3.4.2 is your build/source tree, and
/user/sbhatnag/gccv3.4.2 is your installed tree, right?
If so, then the line I gave above would be right.

I guess that would be because of symbols missing from libstcd++,
but cannot tell for sure (missing info).

Going back to your previous mail:

This symbol (m_game) is not part of libstdc++ as far as I know.

So my guess would be that this particular problem has nothing to do with
the libstdc++.la problem above.  Consider looking for the latter problem
either in cppunit or another dependent package.
