gcc 4.4.0: libstdc++.so has undef references to prior gcc versions

[Amitava Dutta]

I recently built GCC 4.4.0 on Solaris 2.10 / SPARC.
The test results are here
  http://gcc.gnu.org/ml/gcc-testresults/2009-05/msg02684.html

The libstdc++.so that was built has many UNDEF references 
to symbols corresponding to prior versions of GCC.

Why is that so and how do I correct that?

I'm trying to build GhostScript 8.64 using this compiler
and encountered this error:

/usr/local/gcc-4.4.0/lib/gcc/sparc-sun-solaris2.10/4.4.0/../../../libstdc++.so: undefined reference to `_Unwind_GetIPInfo@GCC_4.2.0'

On examination, I noticed that the libstdc++.so has many
unresolved references to prior versions of GCC,
as the screen shot below shows.

Summary of test results for libstdc++
(from the link referred above) is

        === libstdc++ Summary ===

# of expected passes        5750
# of unexpected successes    2
# of expected failures        80
# of unsupported tests        385


How to fix the libstdc++.so so it does not contain reference
to those prior versions of GCC ?

Thank you.

Best regards
Amitava Dutta
