Hello Bill,

Greetings,

What is Compiler Warning C4430
==============================

Compiler Warning C4430  

Error Message
missing type specifier - int assumed. Note: C++ does not support default-int

This error can be generated as a result of compiler conformance work that
was done for Visual C++ 2005: all declarations must now explicitly specify
the type; int is no longer assumed. See Breaking Changes in the Visual C++
2005 Compiler for more information.

C4430 is always issued as an error. You can turn off this warning with the
#pragma warning or /wd; see warning or /w, /Wn, /WX, /Wall, /wln, /wdn, /wen,
/won (Warning Level) for more information.

Example that generaes C4430
==============================
The following sample generates C4430
========================================

// C4430.cpp
// compile with: /c
struct CMyClass {
  CUndeclared m_myClass;  // C4430
  int m_myClass;  // OK
};

typedef struct {
  POINT();   // C4430
  // try the following line instead
  // int POINT();
  unsigned x;
  unsigned y;
} POINT;

Breaking Changes in VS 2005:
==============================
Compiler will not inject int as the default type in declarations
Code that is missing the type in a declaration will no longer default to
type int the compiler will generate Compiler Warning C4430 or Compiler
Warning (level 4) C4431. Standard C++ does not support a default int and this
change will ensure that you get the type you really want.
