If you're using libstdc++.a, you are not writing C. There is no support
for C++ in the backend, and I would strongly advise not trying to use
it, as any of C++'s moderately interesting features like exceptions will
not play nicely with the backend environment.
Unfortunately, we're also using a second library (OpenBabel) that is written in
C++. A good portion of the code I've written is a wrapper layer that hides the
C++ objects and presents a simple C wrapper that works for Postgres.
