I've had similar problems with the g++ compiler under Cygwin32 17.1 with 
a class inside of a normal class.  It was for a school project and 
compiled successfully on the g++ compiler on UNM's AIX machine.  For some 
reason, Cygwin's g++ does not like a class within another class.

My situation was that the the sub-class was declared inside the private 
portion of the main class.  The sub-class was only used in the 
constructor of the main class and nowhere else.  However, the compiler on 
Cygwin32 complained that the sub-class was private when it was accessed.

(Yes, I know that declaring in a class in private that is only used in 
the constructor is very odd, but that's the kind of code this professor 
wrote and wanted us to use.)

I have created other classes within classes in other school projects and 
seen it in text books, so I figure it's valid C++, but Cygwin doesn't 
always accept it.


See ya around the Mulberry bush.
