That isn't going to help, as the clang linker devs don't look there.

That looks like linker output, and thus not a problem with the D toolchain. I guess that the linker you're using also has a suggestion feature. A quick Google tells me you're using a Mac?

lol... that will teach me to reply before reading more carefully. :-P T -- Doubtless it is a good thing to have an open mind, but a truly open mind should be open at both ends, like the food-pipe, with the capacity for excretion as well as absorption. -- Northrop Frye

I'm so used to D suggesting symbols that I didn't think this through, even though I remember seeing 'ld' in the output :-) Yes, llvm/clang on a Mac.
