> Implicit enum to int conversion is not provided for a scoped enumeration.
That said it is strange that gcc also rejects a plain enum:
markus@x4 /tmp % cat foo.cpp
enum A
{
n = 3
};
int
foo()
{
int A;
return A::n;
}
markus@x4 /tmp % g++ -c -std=c++11 -O3 foo.cpp
foo.cpp: In function ‘int foo()’:
foo.cpp:10:10: error: ‘A’ is not a class, namespace, or enumeration
return A::n;
^
