Compiler Error C2626

'identifier': a private or protected data member is not allowed in an anonymous struct or union

A member of an anonymous struct or union must have public access.

The following sample generates C2626:

// C2626.cpp
int main() {
   union {
      int j;     // C2626, j is protected
      int k;     // C2626, k is private

To fix this issue, remove any private or protected tags:

// C2626b.cpp
int main() {
   union {
      int i;   // OK, i is public
