I have been picking up messages elsewhere to the effect that

a) gcc __complex__ support "is broken" -- people are saying that whereas
   the basic arithmetic operations seem to work OK, complex functions do
   not work;

b) g++ does not support __complex__;

c) All this is causing serious problems for people who use g77 (which relies
   on the gcc __complex__ support);

d) The gcc maintainers are working on it but there's no completion date as
   yet.

For what it's worth ...
