>Description:
G++ does not enforce the following rule:
"A name nominated by a friend declaration shall be 
accessible in the scope of the class containing the friend
declaration"
This is a quote from 11.4.7 of the 2 December 1996 draft.

IMHO this is a bad rule that gcc may chose not to implement,
but it should at least be optional. Some compilers do 
enforce this rule.

State-Changed-Why:
    You are correct in reading the standard, and that friend
    access should be checked. You are also correct in asserting
    it to be a bad rule. So bad in fact that C++ defect report
    209 changed it. g++ uses 209's (proposed?) resolution.
