On some systems, `gcc -shared' needs to build supplementary stub code for constructors to work. On multi-libbed systems, `gcc -shared' must select the correct support libraries to link against. Failing to supply the correct flags may lead to subtle defects. Supplying them in cases where they are not necessary is innocuous.
Future versions of GCC may zero-extend, or use
