No, I wasn't sure either, hence I never promoted this to stable. I've 
since realised I need extra configure options, but it doesn't build any 
more, sadly. See my "help wanted" messages to the list for more details 
if you like. I'll give it another go at some point. Unfortunately I 
don't think I really have the time or skill to sort out the compilation 
issues.

I think this might have something to do with sys/epoll.h being missing, 
if memory serves. I think that might simply be something that's not 
available on Cygwin, I'm not sure.

I wonder if a build of wxWIdgets 3.2 might fix the problem. I shall give 
that a go. Unfortunately due to the stack watcher being unsupported on 
Cygwin (IIRC), newer versions of wxPython may be a no-go.

Excellent, I shall test that.
