(You use "module" a lot, here and in the patch; just "object file" would be clearer I think. "Module" has a specific (and different)( meaning in many contexts.) > 2) I turned off GNU attributes for building the shared library or for > building the IBM 128-bit long double support. It's not clear to me what error disabling setting it for the static library avoids? Not that it *hurts* of course. Do you have an example for this? Anyway, okay for trunk (and backports later).
