User(s) can reproduce this bug

The following enum generates one warning per enumeration value:

typedef enum _StdTaskDialogIcons : short int
{
    TDIconWarning = -1,
    TDIconError = -2,
    TDIconInformation = -3,
    TDIconShield = -4
} StdTaskDialogIcons;

According to several people, the enumeration is OK and should not pop the said warnings. See http://social.msdn.microsoft.com/Forums/en-US/vclanguage/thread/fc45de2d-e516-4162-9ec4-de5fddc6681f and http://www.cplusplus.com/forum/general/44367/ for details on it from other language experts.

FYI: I found this problem in Visual Studio 2008, but I was not given the option to post this bug for any other version of Visual Studio other than 2010.

Details (expand)

Visual Studio 2010

Just use the enumeration in a simple C++ application.

Windows 7

One C4341 warning per negative enumeration value.

No C4341 warnings as the enum has been deemed as correct C++.

Hi,
A fix for this issue has been checked into the compiler sources. The fix should show up in the next release of Visual C++.
This is a redundant warning. You can safely suppress it.
