Before std::strings can be used, dealing with a persistent string or
strings for "C" locales needs to be done. I couldn't figure out how to
do this, so I switched. I posted about this on the libstdc++ list, and
there were no other suggestions.

For what's being done here, std::strings are probably overkill, IMHO.
Reasonable people may differ, and do.

If you're worried about exception-safety, you can always add try/catch
blocks around these allocations.
