DllMain is a default name, not a required name.
You could just rename them and add /entry to the linker command line, eg /entry:AwtDllMain

I'm not sure it seems right to have every static destructor need to know what needs to be done to exit the DLL.
I do read your comment about not knowing when the static destructors are called vs the DllMain on shutdown, but surely this *is* well defined ?
