Fixes #134

@balamurugana Ping :)

I am trying to reproduce the error with Github CI by PR #141. If I include windows.h, it works without this PR and including wingdi.h fails with other errors.

[kobalicek]

The failure doesn't seem to be caused by minio-cpp at all. I'm not a windows expert, but I think that since <wingdi.h> doesn't include any other headers it cannot be just included without including others first - most likely at least <windef.h>. WinAPI is old and usually people just include a super header <windows.h> to get most of the core stuff.

PTAL @balamurugana

@harshavardhana We need a working reproducer of the issue. Please refer #141

[kobalicek]

That's a bad reproducer - create a fresh project and include <wingdi.h> and you will see the same failure.

The change is actually solid - it creates the right symbol (without A or W suffix) and then offers inlines in case <windows.h> was included. But it's transparent for users.

@kobalicek Could you add below test case for this PR?

@kobalicek ^^ PTAL in-case you missed.

Just for posterity, this is how I include "windows" in my app

#include <SDKDDKVer.h>

#define WIN32_LEAN_AND_MEAN
#define NOMINMAX
#define _WINSOCK_DEPRECATED_NO_WARNINGS 1

#include <windows.h>
