--- Comment #2 from Martin Storsjö <martin at martin dot st> --- (In reply to Jakub Jelinek from comment #1) > Is mingw really using GNU symbol versioning? That ought to be an ELF only > thing and this is guarded with #ifdef _GLIBCXX_SYMVER_GNU. It's not actually using GNU symbol versioning (indeed, that's an ELF concept), but for some reason, a x86_64-w64-mingw32 build of libstdc++ do end up with "#define _GLIBCXX_SYMVER_GNU 1".
