Bug ID: 42602
           Summary: ::CompareItem(LPCOMPAREITEMSTRUCT lpCompareItemStruct)
                    bad sort compared to Windows
           Product: Wine
           Version: 2.3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: user32

Let's have this MFC code:

class CIconListBox : public CListBox

...

int CIconListBox::CompareItem(LPCOMPAREITEMSTRUCT lpCompareItemStruct)
{ 
    CIconListBoxItem *Item1;
    CIconListBoxItem *Item2;

Item1=(CIconListBoxItem *)lpCompareItemStruct->itemData1;
    Item2=LastItem;

/*
    CompateItem is called immediately after AddString which does not contain
any info for sorting. Pointer to data is set after AddString by calling
SetItemDataPtr.
    This function thus relies on undocumented fact that Item2 is always last
added item.
    Item1 has correct pointer..
    */

//Item2=(CIconListBoxItem *)lpCompareItemStruct->itemData2;

//nejdriv rozhodne priorita
    if (Item1->m_sortprior>Item2->m_sortprior)
        return -1;
    if (Item1->m_sortprior<Item2->m_sortprior)
        return 1;

if (wcscmp(Item1->m_szItemName,Item2->m_szItemName)>0)
        return 1;
    else return -1;
}

Result in Windows: sorted OK
Result in Wine: reverse sorted.
