I'm writing a C extension for numarray and am puzzled about the idiom

Hi,
I'm a newbie and trying to understand event handling in c#. I have

The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
