I presume it is a different project! [Animated GIF]

Where does 'mingw.exe' come from?

Problem solved thanks to discussion at https://stackoverflow.com/questions/59845249:
MinGW is not MinGW.
Instead of mingw.exe, I now use x86_64-w64-mingw32-gcc from http://www.msys2.org.
With this, dumpbin reports
     Symbol name  : foo
with no underscore, and VS succeeds in linking.
