64-bit Build Issue on Windows when Building into NGINX.exe

[justdan23]

Discussed in https://github.com/stnoonan/spnego-http-auth-nginx-module/discussions/135

^{Originally posted by **justdan23** December 14, 2022} I'm trying to build NGINX using Visual Studio 2022 and MSYS2. I'm able to build all of the stock NGINX with OpenSSL, PCRE2, and Zip entirely with x64 for Windows.
However, after I built the KRB5 MIT SDK for Windows to create the SDK folder containing the gssapi/gssapi.h header file, when compiling this SPNEGO NGINX Module, I am running into an issue with the includes not properly picking up the definitions which should appear if the DEFINEs are in place for MINGW. It's as if it is thinking it is GCC when reaching this module's source code for inclusion in NGINX.exe?
Thoughts? ``` Microsoft (R) Program Maintenance Utility Version 14.34.31937.0 Copyright (C) Microsoft Corporation. All rights reserved.
