Dennis Heimbigner d3f6c126b6 Fix Mingw versus XGetopt (again) 
re: https://github.com/Unidata/netcdf-c/pull/2003#issuecomment-847637871

Turns out that mingw defines both _WIN32 and also defines getopt.
This means that this test:
````
#ifdef _WIN32
#include "XGetopt.h"
#endif
````
fails on this error:
````
../include/XGetopt.h:38:24: error: conflicting types for 'getopt'
````

Fix is to replace
````
#ifdef _WIN32
with
#if defined(_WIN32) && !defined(__MINGW32__)
````
