Int-parameterized template with hexadecimal value : link error "1 unresolved externals"

When I specialize an int-templated function with a negative value defined in hexadecimal, Visual Studio 2010 give me a strange "1 unresolve externals" link error.

Still it works fine if:

1. I define the negative int value in decimal form.
2. I define the template argument with "unsigned int" instead of "int".
3. I use directly "DefaultMsg" templated-function. I.e. it only fails when I use "NewMsg" templated-function which calls "DefaultMsg" templated-function.

Then I have some workaround here, but I still do not understand what is going wrong. Am I doing something bad ? Or is it a tricky compiler bug/limitation case ?

Here is a sample code:

// Compile condition: define a code in hexa or decimal
#define DEFINEHEXANOTWORKING    1

// Code
#define CODE1   1
#define CODE2   0x2
#if !DEFINEHEXANOTWORKING
    // Here define a negative code in decimal mode
    #define CODE3   -1
#else
    // Here define a negative code in hexadecimal mode
    #define CODE3   0xFFFFFFFF
#endif

// Default message declaration
template<int r> __forceinline const char* DefaultMsg();

// Default message specialization
template<> __forceinline const char* DefaultMsg<CODE1>()    { return "Message 1."; }
template<> __forceinline const char* DefaultMsg<CODE2>()    { return "Message 0x2."; }
template<> __forceinline const char* DefaultMsg<CODE3>()    { return "Message -1/0xFFFFFFFF."; }

// New template message
template<int r> __forceinline const char* NewMsg()          { return DefaultMsg<r>(); }

// Main test
int _tmain(int argc, _TCHAR* argv[])
{
    // Print default messages, all working in all cases
    printf("Default messages:\n");
    printf("CODE1: %s\n", DefaultMsg<CODE1>());
    printf("CODE2: %s\n", DefaultMsg<CODE2>());
    printf("CODE3: %s\n", DefaultMsg<CODE3>());

    // Print new messages, not working if defined in hexa mode
    printf("\nNew messages:\n");
    printf("CODE1: %s\n", NewMsg<CODE1>());
    printf("CODE2: %s\n", NewMsg<CODE2>());
    printf("CODE3: %s\n", NewMsg<CODE3>()); // Not compiling line in hexa mode

    _getch();
    return 0;
}

The compiler error:

error LNK2019: unresolved external symbol "char const * __cdecl DefaultMsg<-1>(void)" (??$DefaultMsg@$0?0@@YAPBDXZ) referenced in function "char const * __cdecl NewMsg<4294967295>(void)" (??$NewMsg@$0PPPPPPPP@@@YAPBDXZ)
