In a previous article I wrote:

#Compiling this with CC (cfront version 1.2.1) gives the following

#2 errors

Changing line 7 of the above code to:
        7  class derived: private base {
			  ~~~~~~~
results in a correct compilation.

I thought `class D: B {' and class D: private B {' are always
identical. Or so says BS.

Still baffled.
