Re: Semantic does not correctly show PRIVATE/PROTECTED methods to a class of whom those private/protected methods belong

Hi,

I found that the syntax for friend works if I used:

friend class MySecondClass;

I'm assuming that 'class' is optional based on your example below.  If I 
left it out, it showed up as a variable of type int.

I submitted a change to the parser to correctly parse the friend 
statement without CLASS, and added a test for both with and without 
class and made sure it found private data.

Hopefully this solves your problem.
