SYMPTOMS
_ttoi64 is incorrectly defined in TCHAR.H in Visual C/C++ 5.0.
RESOLUTION
Undefine _ttoi64 and redefine it correctly. For the complete solution, see the MORE INFORMATION section of this article.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual C++ version 6.0 for Windows.
MORE INFORMATION
_ttoi64 is a define that substitutes _atoi64 (if _UNICODE is not defined) or _wtoi64 if _UNICODE is defined. On line 481 of TCHAR.H is the following:
#define _ttoi64 atoi64
this should be:
#define _ttoi64 _atoi64
You may add the following code to your source file to correct the problem:
// _ttoi64 is incorrectly defined in TCHAR.H, so you need to undefine
// it and redefine it correctly to avoid a compile error when
// building a non-Unicode version of your application.
#ifdef _UNICODE
#ifdef _ttoi64
#undef _ttoi64
#define _ttoi64 _wtoi64
#endif
#else
#ifdef _ttoi64
#undef _ttoi64
#define _ttoi64 _atoi64
#endif
#endif
