Compiler Warning (level 1) C4224

Error Message

nonstandard extension used : formal parameter 'identifier' was previously defined as a type

The identifier was previously used as a typedef. This causes a warning under ANSI compatibility (/Za).

Example

// C4224.cpp
// compile with: /Za /W1 /LD
typedef int I;
void func ( int I );  // C4224
