Hi,
I am getting a redefinition of 'vsnprintf' when trying to build a 32-bit gcc
9.5.0 (sjlj/posix) with mingw-builds:

Checking the config.log, I find that there's two issues: one for snprintf and
one for vsnprintf:

I am doing a "plain jane" build on 64-bit Windows 10 Pro with msvcrt. I am not
using ucrt or a versioned msvcrt. This works with a 64-bit SEH build.
