Can you give details of your build errors on win32, please?

Actually Windows is a can of worms and doesn't work properly with cothread, and is likely to only work properly if somebody else lends me a hand, as I don't really have the time to give it the effort it needs.  I have at least the following problems with this platform:

1. select() in Windows only works on sockets.  I had previously fudged my way around this with some WaitForMultipleObjects hacks, but I've not yet figured out how to emulate select() on Windows in a way which works for stdio, pipes *and* sockets, and the latest cothread won't work without support for pipes (though I'm willing to fake this as appropriate).  Alas, I've not take the time to figure this out, and it does not seem straightforward.

2. Compiling on Windows is nasty.  VC++ doesn't support C99, and its assembler syntax is somewhat different, but it would seem that mingw is very much a moving target.  Last time I tried a ming32 build I ended up hacking my Python.h files to get things working and then stopped in disgust.  

It is probably better to bite the bullet and create VC compatible versions of the files in the context/ directory, but I am so reluctant...

3. From spring this year it will have been exactly a decade since I was last employed as an engineer to work on Windows.  I rejoice.  Sorry, but this is my attitude to the platform.  I don't want to say much more, as I'm liable to rant at this point!

I'll answer this in another e-mail, would like to separate the Windows issue from the rest!
