My idea in comment #1 was that if people include <complex> and then <complex.h>
(the order is important), with your suggestion, they won't be able to use
std::complex, so there is little point including <complex>.

Now in C++11, complex.h actually first includes ccomplex, which seems to be an
alias for complex... so there is no way to include complex.h and not complex.
Which seems to imply that at least in C++11, we should just always undef
complex.
