Can you try breaking it down by phases? 1. Preprocessor phase with -E -o file.ii
$ time x86_64-w64-mingw32-g++ -E -o file.ii stoi.cpp; wc -c file.ii real 0m0.172s 719550 file.ii
2. Compile phase (compile output from phase 1) with -c
$ time x86_64-w64-mingw32-g++ -c file.ii; wc -c file.o real 0m0.312s 7368 file.o
3. Link phase, point gcc to the output from phase 2.
$ time x86_64-w64-mingw32-g++ -static file.o; wc -c a.exe real 0m1.950s 11906797 a.exe Also it might be worth noting the starting point - for some reason Cygwin is 4 times larger than Msys2? $ wc -c /lib/gcc/x86_64-w64-mingw32/7.3.0/libstdc++.a 22446354 /lib/gcc/x86_64-w64-mingw32/7.3.0/libstdc++.a $ wc -c mingw64/lib/gcc/x86_64-w64-mingw32/8.2.0/libstdc++.a 5597192 mingw64/lib/gcc/x86_64-w64-mingw32/8.2.0/libstdc++.a -- 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
