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?
That is called symbol versioning and I think it is normal (although I
don't know in what cases gcc uses symbol versioning, I thought it was
only with the gnu linker).
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@xxxxxxxxx'
Which libgcc_s.so.1 got loaded when you had this error? It looks like the
kind of thing that might happen if you use a recent libstdc++ with an
older libgcc_s.

Looks good (no unexpected failure).
