How to make the gem?

Hi all,

I wanted to test thin at work, on Windows with VC++ 2005, but I can’t
install it because I got an error with the
compilation of em.cpp, because EINTR was not included in the
“project.h”.

I would like to test thin and use it, but with this bug, I can’t install
it :-).

I can compile EventMachine with ruby ext\extconf.rb and run the
makefile. But how can I generate the gem, because I
didn’t find the gemspec file.

Best Regards,

Stephane
