The general rule is g++/c++ should be used.
The problem you're hitting could be solved (with my libgcc patches) in a
couple of ways...
1) Use gcc/cc -shared-libgcc. c++/g++ adds --shared-libgcc automatically
2) Link the c++ library with -shared -static-libgcc. This one only works
if exceptions only happen within the library.
A C++ library that uses exceptions linked into a c binary is something that
doesn't work in -current atm.
