[Mingw-users] How to generate the _imp_ prefix?

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.

> The library shall be used in a C++ application under Visual Studio.

> foo contains the line

>    Symbol name  : _foo

> So, MinGW does not generate the prefix _imp_. Expectedly, linking the
> dependent application fails because Visual Studio cannot find _imp_foo.
