This is not a bug as gcc is more strict on implementing the C++ standard.
Read <http://gcc.gnu.org/onlinedocs/gcc/Name-lookup.html#Name%20lookup>.
Also since the tree-ssa branch gets merged from the mainline every once in a while, you should try 
the mainline also.
This is not dependent on the tree-ssa so removing the markers.

Subject: Re:  members disappear when inherited from template
 parameter class

This question is likely a very stupid one, but here goes:
I compiled:

template <class T> class a : public T { public: using T::aa; a() { aa = 5; 
}; };class b { protected: int aa; };
a < b > a1;

with
  GNU C++ version 3.4 20030803 (experimental) (i686-pc-linux-gnu)
    which worked
  GNU C++ version 3.5-tree-ssa 20030731 (merged 20030722) (i686-pc-linux-gnu)
    which gives:
p.cpp: In constructor `a<T>::a()':
p.cpp:1: error: `aa' undeclared (first use this function)
p.cpp:1: error: (Each undeclared identifier is reported only once for each
   function it appears in.)
Am I using the wrong cvs-branch (3.4) to test against?  Or am I doing 
still something else wrong?

Thanks,
Stefaan

As I said before the tree-ssa branch gets merged from the mainline.  The problem on the mainline 
was just fixed in the last week so the only way for the tree-ssa to be fixed is to have them merge 
again. (The last merge is in the version, merged 20030722.)
