So, I recommend to keep this flag set for portability.
Hi Takashi, I use Win10 2004 and I can confirm that my program needs those lines when run from cmd but not from mintty. So that behavior change was caused by a change in Win10, not in cygwin. As for cygwin 3.2.0-0.1, then I can only report for now that: make v4.3 works correctly, x86_64-w64-mingw32-c++ v10.2.0 works correctly, mintty v3.4.6 works correctly, bash v4.4.12(3) works correctly, my simple C++ console program works correctly. -André Bleau -- 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
