I think a macro would better handle it than not using %zu, but that is
out of the scope of this patch.

This patch is only relevant to future MinGW-w64 releases, which
have a working vsnprintf, etc. implementation. Regular MinGW, MSVC,
and MinGW-w64 version 2 and earlier, will continue to work the same,
and correctly.

Perhaps we could add the MinGW runtime version to the "compiler
version" output under the 'ffmpeg -version' output? That would
in a lot more cases than this.

"Bikeshedding" ? ;)
