I use CMake. I should try with Autotools. I would be curious to see your
ldd output for your binary if you've compiled with libc++. Does
libstdc++ also show up in it?

It took me a while to figure out this was going on, but Kornel helped
fix things for the bundled Hunspell (even for the bundled Hunspell we
were trying to link against the system Hunspell in CMake). I'm planning
to search for materials to understand the std::string API. I'm confused
as to why this only shows up when linking against libhunspell.
