the code project

#include "stdafx.h"
#include <windows.h>
#include <assert.h>

int _tmain(int argc, _TCHAR* argv[])
{
    DWORD flags = NORM_LINGUISTIC_CASING|FIND_STARTSWITH;
    int nResult =
FindNLSStringEx(L"en-US",flags,L"x-oss-security-token",0xe,L"x-oss-",0x6,0,0,0,0);
    printf("FindNLSStringEx Result = %d \r\n", nResult);
    assert(nResult == 0);
    return 0;
}

the code in Windows print: "FindNLSStringEx Result = 0"
but in Wine print: "FindNLSStringEx Result = -1
Assertion failed: nResult == 0, file .\FindNLSStringEx.cpp, line 13
"
FindNLSStringEx is very important for C#, because it is the basis of the String
class, StartsWith, EndsWith, IndexOf all rely on it to achieve. So hopefully
you guys can test it rigorously, thanks a lot. In addition, I found a lot of
bugs and fixed them myself, how can I submit these PRs?
