Hi all,
please find in attach the compile errors I got....
this is too cryptic for me too see the link to an actual error in my code...
The only modification I made to a compilable code is to use the numpy buffer
notation for locals in a cdef block which I attach in a second file.
When I looked at it it was actually something else than I thought and
much simpler to fix. Fix is now up in the repositories (or apply what I
attach yourself to avoid waiting for a release).
Thanks to you and Hoyt for reporting this!
