Hello Cython-devel, I noticed that now unsigned constants like DEF foo = 1 become 1U in the C source code. This change (i.e. commit ea6414cd293ba2134c3df5b37b158d8e3db79083) broke Sage. I haven't managed yet to actually isolate why this change broke something. Was this change of 1 to 1U intentional? Why was it done? Jeroen.
