VerifyVersionInfo関数でOSのバージョン情報を調べたいのですがコンパイルエラーが出てできません

環境:
windows 7
mingw(gcc)

ソース:

#include <windows.h>
#include <stdio.h>

int main()
{
OSVERSIONINFOEX OSver;
ULONGLONG condition = 0;
OSver.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
OSver.dwMajorVersion = 6;
OSver.dwMinorVersion = 1;

VER_SET_CONDITION( condition, VER_MAJORVERSION, VER_EQUAL);
VER_SET_CONDITION( condition, VER_MINORVERSION, VER_EQUAL);

if( VerifyVersionInfo( &OSver, VER_MAJORVERSION | VER_MINORVERSION, condition) )
{
printf("ok");
}

return 0;
}

エラーメッセージ:

ver2.cpp: In function 'int main()':
ver2.cpp:12:31: error: 'VER_MAJORVERSION' was not declared in this scope
 VER_SET_CONDITION( condition, VER_MAJORVERSION, VER_EQUAL);

 VER_SET_CONDITION( condition, VER_MINORVERSION, VER_EQUAL);
                               ^

マイクロソフトのverifyversioninfo関数のページを見ると、英語版の方にkernel32.libが必要と書いてあったので、kernel32.libをダウンロードして-lkernel32オプションを付けても同じエラーが出ます。

どうすればいいと思いますか？
