The question is not appropriate for the gcc@gcc.gnu.org mailing list.
It would be appropriate on the gcc-help@gcc.gnu.org mailing list.

The actual problem is happening because g++ 3.4.6 does a better job of
implementating the standard C++ language.  You are falling afoul of
the two-phase lookup rule.  The easiest fix is to change the line to
    T PROC(T x) { this->c1i = c2i; };

Further questions on this topic should be taken to a C++ standard FAQ.
