If I strip the executable, all is well: $ time x86_64-w64-mingw32-g++ -s -static-libstdc++ stoi.cpp; wc -c a.exe real 0m0.889s 845824 a.exe Same with Msys2: # time x86_64-w64-mingw32-g++ -s -static-libstdc++ stoi.cpp; wc -c a.exe real 0m0.718s 835584 a.exe However if I do not strip the executable, the compile time nearly triples and the size increases 10 fold: $ time x86_64-w64-mingw32-g++ -static-libstdc++ stoi.cpp; wc -c a.exe real 0m2.340s 11695660 a.exe Compare with Msys2, where the time only increases 17%, and the size only increases 3 fold: # time x86_64-w64-mingw32-g++ -static-libstdc++ stoi.cpp; wc -c a.exe real 0m0.842s 3001138 a.exe -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
