Bah, who knows what font size I have in my mail reader? ;)

IIRC, -all_load is mostly/only of interest when creating libraries from other (static) libraries, to ensure that all functions/modules get pulled in. I don't really see the interest when linking an application, unless of course you want to enable plugins to dlsym variables or functions that the app doesn't use itself. And I'm not sure if I find that better practice than defining global variables multiple times in public libraries ;)
