greetings,
	while i have used the Complex class in c++, i was pleasantly 
surprised to see that it is implemented in c as well (info gcc (c 
extensions)). however, small sample programs with this yield wrong 
answers for example 

....
__complex__ z;
z = 0.0 + 0.7fi;
.....
zz = log(z);
.....

gives a wrong zz. i would be grateful if users of __complex__ in c could 
share their experience on this. would it correct to conclude that while 
simple algebraic manipulations are implemented, math functions are not? 

with warmest regards
gurunandan
