Incidentally, my understanding is that the C++ standard says that dynamic initializers only need to be run before the first time the module is accessed (not necessarily before main()). Thus, if your program contains no symbols referring to the module, then it will never be accessed, and dynamic initializers are not required to be run at all. Therefore GCC's behavior is arguably correct. A work-around is to add dummy calls to your main() function to each module that you want to force to be linked in.
