I do not get those warnings. In our case, I think that the C header
files being used are the ones that come bundled with our compiler.
I only have vague knowledge of how things fit together, but perhaps
it's just a matter of which MinGW version you are using?

I'd rather avoid that, since the warnings are non-fatal in the release
environment, and also because others do not have this warning.
