[Doxygen-develop] [BUG] "friend class" causes error in "Friends" section

[Morten E. <mo...@si...>]

Hi,

I think this is a bug in the C++ parsing: when using "friend class
SomeClass" in a header file, like this

---8<---- [snip] --------8<---- [snip] --------8<---- [snip] -----
class MyClass {
private:
  friend class SomeClass;
};
---8<---- [snip] --------8<---- [snip] --------8<---- [snip] -----

..then "class SomeClass" shows up in the "Friends" section of
MyClass's class documentation. If I understand the purpose of the
"Friends" section correctly, it is supposed to only contain a list of
friend _functions_.

A friend _class_ is a completely different thing, and is something
that should only be of interest for the implementation -- ie it's a
detail that should not be present in the class doc.

(Also, Doxygen spits a bogus warning when hitting "friend class
SomeClass": "Warning: Member SomeClass of class MyClass is not
documented.")

I found this problem when upgrading from 1.2.something to 1.2.15, and
it is still present in 1.2.17.

Regards,
Morten
