Major Description
These patches have been sitting around for nearly a year, but I've rebased them onto the trunk and tested them again. They cover several classes of fix:
- minor build improvements
- minor tweaks to feature tests
- enabling stricter compiler warnings, and then fixing those warnings
- fixing mismatched delete/delete[] (bad)
- adding missing virtual destructors (bad)
- removing unused variables
- removing unused variables conditionally when used conditionally
- removing cast warnings with appropriate C++ const/static/reinterpret casts
Most of the fixes are tiny one-liners to fix warnings.
