Can't include D2D1

Question

I feel like this should work...

#include <d2d1.h>
int main ()
{
    return 0;
};

...but it comes up with a bunch of this...

C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include\dxgi.h|286|error: '__in' has not been declared|
C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include\dxgi.h|286|error: expected ',' or '...' before '&' token|

C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include\dxgi.h|307|error: expected ',' or '...' before '&' token|

...and so on.

I'm using MinGW on Code::Blocks compiling C++ for Windows. Right now my only compiler option is -mingw32. If you know what this result might mean and how I can fix it in the C::B options or where ever I need to change something, that would really help.

-- UPDATE --

I blank-defined what I assumed to be troublesome Visual Studio macros.

#define __in
#define __out
#define __in_opt
#define __inout
#define __in_bcount(x)
#define __in_ecount(x)
#define __out_ecount(x)
#define __out_bcount(x)
#define __out_ecount_part_opt(x,y)
#define __out_bcount_opt(x)
#define __in_bcount_opt(x)
#define __in_ecount_opt(x)
#define __out_ecount_opt(x)
#define __out_opt
#define __inout_opt
#include <d2d1.h>
int main ()
{
    return 0;
};

However, now in d2d1.h I'm still getting this issue:

C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include\d2d1.h|1246|error: expected initializer before ':' token|
C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include\d2d1.h|1269|error: expected initializer before ':' token|

Since it's not a preprocessor issue, I want even less to tamper, since I'd have to change around the actual header. Any ideas on how to fix this?
