On AIX and other platforms without weak symbol support, templates need to be instantiated explicitly and symbols for static members of templates will not be generated. + +@item +On AIX, GCC scans object files and library archives for static +constructors and destructors when linking an application before the +linker prunes unreferenced symbols.
