Summary:                    libstdc++.so.6.0.10 doesn't see libgcc_s.so.1
/opt/csw/gcc4/lib/libstdc++.so.6.0.10 looks for libgcc_s.so.1 dependency in
system runtime linking environment, instead of linking to

For the library to be self-sufficient the runtime linker path must be
compiled into the shared lib. No RUNPATH there:

However, as libstdc++.so.6.0.10 is always linked to a binary, that binary
itself needs to have this runtime linker path also. So there is a slight
flaw inside the shared lib which should be fixed some time, bit it
shouldn't be visible when you compile something as '-R/opt/csw/gcc4/lib' is
