A quick test appears to reveal that no, the shared libraries will not take advantage of the version of libstdc++ which is statically linked with the main program. Attempting to run my program on older systems now results in: bin/myprog: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ../lib64/libicui18n.so.62) Hm. Bummer.
