That's not really an option, as Ada links its static runtime by default and tries to avoid external dependencies by default. > No, it's not possible to let people safely 'just use EH' with no > extra work.

IIUC, that passing nothing is neither equivalent to -static-libgcc nor to -shared-libgcc is a feature, right? I know Darwin didn't invent it (IIRC Linux did) but that's not a valid excuse. :-) And the "neither -static-libgcc not -shared-libgcc" on Darwin is not compatible with the "neither -static-libgcc not -shared-libgcc" on Linux. OK, I guess we have no other solution than defaulting to -static-libgcc for Ada on Darwin. Thanks for your feedback. -- Eric Botcazou
