Just to clarify that "no", it seems that commit matches what I expect: the default is ms_abi, and sysv_abi overrides that and is accepted without warning. I believe clang *would* emit a warning for explicit ms_abi on Windows (MSVC/MinGW, and soon Cygwin will follow that too). -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
