Yes; sounds more like an issue for GCC :) I mean you don't have to tell it to link against c library or c++ runtime libraries... and it IS pthread specific so it's not like there's going to be some alternative provider for such services. using MinGW under linux to get a windows output it links automatically to a 'winpthreads.dll' which then becomes a runtime requirement... so it's not impossible for the compiler suite to do. > > On Thu, Feb 4, 2016 at 11:53 AM, rpela...@archlinux.info > <rpela...@archlinux.info> wrote: >> >> I believe that doesn't have anything to do with C11 flags.
