You are using mkrf instead of mkmf, so things work a bit differently.

$ cat extconf.rb
require 'rubygems'
require 'mkrf'

dir = File.dirname(__FILE__)
Mkrf::Generator.new('json_ext', "#{dir}/*.c")
$ cat > extconf.rb
require 'mkmf'
create_makefile "json_ext"
$ ruby -I ~/usr/ruby-mingw32/lib/ruby/1.8/i386-mingw32 extconf.rb
/home/batsman/ruby-mingw32/lib/ruby/1.8/i386-mingw32/rbconfig.rb:7: ruby lib version (1.8.4) doesn't match executable version (1.8.5) (RuntimeError)

Thanks for demoing this. I'll give it a shot.

What lie ray-ray? I said the government is the majority shareholder
of GM and as such effectively controls the company. You can quibble
about if there's a difference between "controlling" the company and
"running" the company, but the government has control of GM.

I never said there was a government employee running GM. It's a shame
you have such honesty problems.
