Yes. -single_module will make just one module, using gcc -r first on your objects will not. The stuff in .a's (such as libgcc.a and libstdc++.a) will be in separate modules. This does not actually make too much difference in the static initializers not being called problem, but does affect the speed of the dynamic linker (single_module is "faster" in general than multi-module, but is nigh on impossible to debug).
Also note that -single_module only appeared on the december 2002 developer tools (if I recall correctly) and is not available on prior versions of the linker. The gcc -r crap will work on all systems.
