I have testet my program with a 2.95 and several 3.x versionsions of gcc.
The lastet version I have is 3.3.3.
All versions gave the same result.
What was the critice you mentioned above? I can not imagine a sitation in
which I would need the naive implementation. But I think it can not be
good that if I get different result for complex and real arithmetic. If
the number are the same real numbers.

As you mentinon it if have missed the specilization at the end of
std_complex.h. Sorry. I still think that we should have and other
implementation for complex<floating_point>, but I cannot change the code
of __complex__ T in the complier.
