This is now fixed in 4_6-branch too in C++03 mode, not in C++0x mode, where we
would need list-initialization of __complex__.  If people believe we can /
should do something else in the release branch, I'm all ears: if for example
people consider a better trade-off for the branch removing the constexpr from
the constructor in order to initialized in the body for C++0x mode too, I'm ok
with that.
