Build options are set via a build_options file in the build directory instead of being inferred from the name of the build directory. Options are passed to C++ via config/*.hh files instead of via the command line. Build option flags are now always defined to 0 or 1, so checks must use '#if' rather than '#ifdef'. SConscript: MySQL detection moved to SConstruct.
