            else:

compile fine with downgrade to cython2-0.19.2-1

[Antoine Martin]

r5271 removes the offending line, which didn't do anything anyway. (will backport to v0.11.x)

Hopefully, this is the only problem with Cython 0.20, which I have only tested with win32 and OSX...

[Antoine Martin]

Backported in r5273 (will be included in 0.11.2), tested on Ubuntu 13.10 and Fedora 20, closing.

Seems to be another one

I added a comma and recompiled. It seems to have worked is this correct?

I've attached the patch

[Antoine Martin]

Yes, applied in r5291, thanks.

(this one broke all versions of Cython - not just 0.20)
