Compiler Error C2467

illegal declaration of anonymous 'user-defined-type'

Remarks

A nested user-defined type was declared. This is an error when compiling C source code with the ANSI compatibility option (/Za) enabled.

Example

The following example generates C2467:

//C2467.c
// compile with: /Za
int main() {
   struct X {
      union { int i; };   // C2467, nested declaration
   };
}
