Re: Building under Cygwin

[David Chisnall]

If you have time to look at libobjc2 under Windows, I'd be grateful for someone 
with Windows dev experience to take a look.  There's some basic support there, 
but it's not really very good, and I don't think it will actually build on 
Windows.  I can provide advice, but don't have a Windows machine for testing.
