GCC still accepts the code when it is ill-formed as explained
here:https://stackoverflow.com/questions/77932976/why-is-a-type-alias-not-allowed-to-be-a-friend-class-name-in-c/77932987#77932987
Here is a demo that shows that gcc accepts the invalid code:

In C++0x the testcase is still ill-formed, but changing "friend class" to
"friend typename" makes it well-formed. I'm not going to give an error for
this usage until the other usage is implemented.
