as it happens the current state breaks Darwin bootstrap, there’s a “set but unused”. fixed by https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581016.html if that fix is acceptible, then we can backport it to the branches too - which will also be broken; if not then we should shake down an alternate soon. > I had a look at darwin.h, and it occurs to me that you probably will be > wanting -static-libphobos added there as well, which means moving that option > to common.opt. could be; but the fix above at least provides independent control over the static-libstdc++ situation (which tends to be more problematic on Darwin, since libstdc++ (latest) is always co-installed with the system’s (very old) version.
