Cython throws a lot of warnings for STL complex types

[torr...@gmail.com]

Hi,
STL's complex data types generate a lot of warnings for me. Calling cython on a pyx file with only the following lines of code:

cimport cython

from libcpp.complex cimport complex

or:

cimport cython

cimport libcpp.complex

from libcpp.complex cimport *

I get 50 or so warnings of type

warning: PATH.../site-packages/Cython/Includes/libcpp/complex.pxd:82:21: Function signature does not match previous declaration

This happens on different machines with Cython 0.26 and 0.23 setups.

For other STL types, like vector this does not happen.

Any help on what this is about and how to fix it would be appreciated.
