Installing from the git or rubygems repositories no longer works (currently) under 1.9.2 or 1.9.3 (confirmed still broken on 2012-June-22). Instead, you need to simply:
gem install eventmachine --pre
gem install thin
Note that on 2012-June-18 the current prerelease was renamed to 1.0.0.rc.1, so there is a possibility that 'soon' the version that works with Windows will become the official release and this will no longer be a problem.
If you try to build the gem under 1.9.2 from the github repo you may see this (included for search engine hits):
C:eventmachine> rake build
(in C:/eventmachine)
cd ext
C:/Ruby/bin/ruby.exe extconf.rb
checking for rb_trap_immediate in ruby.h,rubysig.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details.
If you try to install the gem under 1.9.3 from the rubygems repo you may see this (included for search engine hits):
C:>gem install eventmachine
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
