Dear Mark,
thanks for looking into it. However, in the 3.0 release your fix seems to
not be working: for c++615, which is kind of a small form of
optimization/2938, I still get 1009 calls to Point::operator() (which is,
as you said, not only a problem of optimization, but also a correctness
issue as the operator is not marked constant). This is both on Sun
Solaris2.7 and Linux.

Optimization/2938 still takes infintely long. I double checked, but my
gcc3 sources have your patch to the problem incorporated. Do you know what
is going on?

Regards
  Wolfgang
