| >Description:
| This might not even be a bug but...  The sample code provided
| shouldn't compile (if it does, mail me and I'll send you the 
| code in which I originally discovered it), I don't remember 
| the error message, but try it.
| >How-To-Repeat:
| //start fawhack.cpp
| class Y;
| 
| class X{
|   friend Y;
| public:
|   X():xmember(666){}
| private:
|   int xmember;
| };
| class Y{
| public:
|   X x;
| };
| main()
| {
|   Y y;
|   y.x.xmember=69696;//error
| }
| //end fagwhack.cpp
| 
| Just compile this code like:  g++ -o fagwhack fagwhack.cpp
| No special options or anything.
| >Fix:
| The way I fixed it was just to make a method in class Y like
| this:
| 
| public:
|   inline int xmember() const {return x.xmember}
| 
| but I think this is particularly ungraceful and should be 
| able to be done in the way I originally tried

Hi,

This is not an Autoconf bug.  The interface you used to report this
bug sets the default category to `Autoconf' and you forgot (most
probably just even see the field) to change it to GCC.

I think the GCC team should change this page, this is the 5th or 6th
time this happens.

Regards,
