We build our own GCC (after applying that patch), but I haven't checked whether it used UCRT for cross-building libstdc++. Ideally we wouldn't need a -mcrtdll option, but enforce it directly in the compiler. I also realise we haven't made a release since this change, so it's still time to fix it. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering
