RFR 6722928: Support SSPI as a native GSS-API provider

[Weijun Wang]

Hi Nico,

Can you provide more explanation on below? I have't touched C/C++ for quite some time and I really forgot what extern "C" is for. I included it here only because it's also in gssapi.h and I thought I should make the declaration and implementation consistent.

The getenv line compiles fine, and I am using VS2017.

And I don't intend to make this C.

So what's the formal way to do all these?

Thanks,
Max
