We have use cases of both dynamic and static linkage for the

Are you building with "mingw32" as the target (not as the SDK), and it
works there? I wonder why it only fails for the SDK build and not the
target build? If that is truly the case, then yes I suppose it should be
the "sdkmingw32" override. The strange thing about that (and why I
thought it was incorrect) is that we have a few recipes that disable
shared libraries and/or enable static with just the "mingw32" override,
which is why I assumed it was a general limitation of MinGW, not just
the SDK. I looked through the recipes, and it does seem more apparent
that it is inconsistent, with a few recipe using "mingw32", a few using
"class-nativesdk:mingw32", and a few using "sdkmingw32".
I see two classes of problems based on my engagement with the mingw32.
Some recipes just don't build without using the static method for
the SDK and the target both. (abseil-cpp is one of them)

The nativesdk problem for grpc and protobuf is a silent failure. Even
though we are able to build the binary, we get a binary that just
doesn't work on windows. (crashes upon execution)

I still would like to be able to static/dynamic link grpc/protobuf for
my target using the SDK.

Anyway, please send a V4 if it needs to be changed, and I apologize for
changing it unnecessarily :)
Will do.
