It's really strange. For 3 last years I use 'g++ -shared' for creating shared libraries
in solaris. That's is especially important if you have templates.

I've never had any luck using gcc to create a shared library. It never seemed
to work for me (maybe I was just doing it wrong). Using ld has always worked
fine. This has always been on Solaris. I use gcc/g++ for linking a standalone
program linking to the shared library and that takes care of libstdc++ and
libgcc.
