    $ 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
