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
