Building on Linux Debian Etch 2.6.18-6-k7 #1 SMP Thu May 8 08:09:57 UTC

Compile error in Modules/cmathmodule.c

Detailled error message follows :

Checking previous function in the file cmathmodule.c, it seems that you
have to declare line 916 :
Py_complex z,r;

After this correction the compilation is ok. I do not test the function
itself, I just try to have the code compiling.
